Altogether the milk of 212 cows was examined, 848 samples from each quarter of the udder, and 212 aggregate samples.

The ring reaction is less sensitive than the Khedlson reaction with whole milk, and even more so with whey. The content of antibrucellosis agglutinins in milk of cows with brucellosis does not depend on their content in the blood and is inconstant, as they may disappear and appear anew, and may be contained In all parts of the udder or only In separate quarters.

(USSR) ABSTRACT: This report was delivered at the Inter-vuz scientific- technological conference held at MVTU imeni Zaumana in January 1958. In foundry practice, the experimental formula of N.P. Akeenov described the dependence of the mixture cc.mpa., 1; ness -talue ~ g/cu cm on the pressure p kg/eq cm under the pressure block during pressing: J= I + CP 0.25 whereby C is the compressibility factor of the mixture. The strict correapondence of the mix- ture density to the external load value indicates, that the external forces acting on a mixture are opposed by internal forces whose magnitude is determined by the mixture properties and the external pressure. There- fore, the mixturc comp%cting process should be con- Card 1/3 aidered as a process of overcoming the internal foxcesq The Theory of Com-pacting- Casting Molds SOV/159-58-3-18/31 opposed to a free reduction of the mixture volume. M oompacting Is terminated as soon as the external forces are balanced by the internal ones. Por renew- ing this process an increase of the external forces is required. Por developing more rationp' compact- Ing methode and designs of molding machines, it is ,necessary to have a clear picture of the character of the connections, existing between the mixture proper- ties and those internal forces opposing the mold con- deneation under the influence of different external pressures. In his investigation, the author considers mold and core mixtures as an claoto-viscous compres- sible material with strongly accentuated viscosity properties. He presents equations in a general form for the mixtur, compactness, which express the de- pendance of the degree of mol,,' compactness on the impule magnitude of the external load. He recommends the equations for practical application.

Curve I of Fig.; I shows the change of temperature (t. C) with time (1b,, see) when plate& of chromel and alumel or thickness 0.1 mm were joined. Curve 2 in Fig. I shows the change in the strength (Qavt kg) of the joint with time. The maximum temperature occurred at the time when the strength of the compound had become constant. Zero strength did not coincide with the time of the beginning of the increase in temperature. The results can, be explained in terms of friction. The increase in temperature is caused by heat generated by the relative movement of the two components. When a joint is made, there is no relative movement and the Card 1/3 8669t/004/030 S/180/60/000/00 E021/E335 The Role of Friction During Ultrasonic Welding temperature drops.

As the metal Is poured through the vibrat- ing funnel the walls become coated with a hard layer of metal. This layer is broken by the vibration of overheated liquid metal and solid metal pieces are carried into the mold together with liquid motal, where they melt partly or completely. If no complete melting in reached by the time the metal be- gins to solidify, thene solid, phases become centers of crystallization.

TITLE: Casting thin-wa1led, large-sized panel compounds In green aand-olay molds PERIODICAL: Liteynoye proizvodstvo, no. 8. icg6l, 38 - 39 TEXT: The casting of thin-walled, 1&rge-size panel parts of aluminum and mAgnesium alloys ensures a considerable saving in the weight of these components and in time. On the other hand some difficulties must be overcome, In the first place those, encountered in filling the mold with the liquid metal. In the Soviet Union thin-w&lled panels are cast by successive crystalliiation or extrusion. The latter method Is applied for A.,0.4 (AL4) aluminum alloy sheets 800 x 1,500 x 2 - - 5 mm In size, moreover for AL2 and t4j.5 (M15) alloy panels. However, when apply- ing the method for heat-resistant and high-strength AIB, AL19,B15 (V]5) alloys, hot cracks are forming. In order to establish the cause of this defect tests were carried out at the Liteynaya Laboratoriya MVTU Im. Baumana (Foundry Labora- tory MVTU im. Baumai) and it was found tha*w panel elements 500 X 800 x 3 - 4 mm Card 1/4 N\ 27727 S/128/61/000/008/004/004 Casting thln-walled, large-sized A054/A127 In size could be cast from AL19 and V15 alloys by applying the conventional cast- Ing and using green sand-clay molds. Test panels, 250 x 300 x 2 mm In size were ea%'. using a channel (12 x 12 mm) around the panel which considerably facilitated the filling of the mold. The removal of air and gases from the mold cavities is al3c, impcrtant In this proce3g. When applying 0.3 - 0.4 mm thick inserts on the parting surface of the mold during the assembly, the filling of the mold improved, the ventilation through the narrow aperture at the parting surface of the mold be- came more Intensive. The circumferential channelj the slot-type feeding system operating over the entire periphery of the casting, a high-capacity slag-chamber and a riser with a considerable cross section ensure a great intake of the liquid mtal and an instantaneous filling of the mold. Moreover, ribs formed on the casting also promote a rapid filling of the narrow spaces. The gate and the ven- tilatlon system bnaid on the above prlncipl,~s for casting 500 x 800 x 3 - 4 mm panels are shown. The molding mixtnre used consists of 55 - 6o % nol (Pol) type Tambovak sand, 4;; - 50 % quartz sand and chalk, having a humidity of 6 %ja gas permeability of ~4 units and a compresssion strength of 0.24 - 0.27 kgloW . The bin-!er contained 10 % Tambovsk sand and 90 % burnt sand and had a humidity of 4.5 % and a compression strength of 0.35 kg/cm2. It was found that the applica- Card 2/4 27727 3/128/61/000/008/004/004 Casting thin-walled, large-sized .... A054/A127' tion of inserts at the parting surface of the mold had an adverse effect on the accuracy of the panel dimensions. Therefore, to promote ventilation, Instead of using inserts, 1.0 - 1,5 mm wide grooves were cut in the parting surface al9ng the periphery of the casting. This arrangement required a high casting tempera- ture, (for the AL 4 alloys; 820 - 8300C, for the AL 19 and V15 alloys: 850 - 8600 C). On the other hand the high temperature promoted the formation of cavitAffstin some cases the casting split Into two parts). This could be eliminated by con- trolling the density of the mixture in the upper part of the mold by changing its composition and the intensity of ramming. In this way panels can be cast also from X1849T (Kh18N9T) steel in dry sand molds. The mechanical properties of AL4, V15 and Kh18N9T steel panels meet the standards set. A deterioration of the me- ohanical characteristics could only be observed in AL 19 panels. This was caused by a lack of heat resistance In the metal. When coating the casting surface with hexachlorethane, however, the casting temperature of the AL19 alloy sheets could be reduced from 850 to 7300C. The dimensional accuracy of the castings depended on the assembling accuracy of the mold and on the stability of the bottom plate. During assembling the mold showed a deformation of 0.1 - 0.25 mm, while during transportation (shocks) the deformation of the thickness of the casting attained 0.4 - 0.5 mm (20 - 30 %).

The solidification took place over a rotating cast iron or sand rodp held in a vertiole spindle and lowered into a melt maintained at a constant temperature, Heating of the rod was eliminated by the use of asbestos lining on the end face of the rod where no deposit was noticed.

Ultrasonic vibrations were produced by means of a magnotostrictive generator, the end face of which oscillated with a froquoney of 20 kc/a and an amplitudo of 32 ji; the power input was 2.0 to 2.5 kW. The diameter of the contact face was 22 ram and the ingot-mould diameter was 50 mm. The first Card 1/3 33178 s/ift/61/bdo/oWoo8/020 The breaking-up of grains .... E071/E335 experiments were carried out by decanting tho liquid metal re:-.iaining after different lengths of time. Metallographic examination if longitudinal sections showed that solidification took place from the periphery inwards. The structure irmuediately adjacent to the walls was not destroyed by the ultrasonic vibrations and was still columnar. The remainder of the casting was fine-grainod. It is proposed that the fine grain size is due to nucleation by solid fr-Agmonts broken frorl, the columnar zone under the action of ultrasonic vibrations. Further experiments showed that the columnar peripheral zone was not present0when metal was poured into a mould preliminarily heated to 700 C. In this case solidification begins only from the contact with the ultrasonic instrument. The solid metal so formed is broken up by the vibrations and causef; grain refinement of the cnating. Tho next experiments were carried out by heating the aluminium to 740 - 750 OC and allowing solidification in the crucible in air (cooling rate about 0.5 OC/sec). Froia the moment when solidification temperature was reached, vibrations were introduced into the melt for different lengths of time Card 2/3 33178 S/180/61/000/006/008/020 The breaking-up of arains E071/E335 (from I to 10 secs). The metal was more finely grained with longer treatment time. Tests using a pouring temperature of 740 OC and casting into a steel mould showed that the minimum time required for the vibrations to act was 3-5 sec. With a slower rate of cooling longer treatments with ultrasonic vibrations are reqdired to obtain complete grain refinement. The results confirm that it is advantageous to use vibrations on the liquid metal of a welding bath during clectro-slag or arc-welding of metals.

TITLE; On the problem of the effect of vibration on solidification of alloys in castings PERIODICAL: Fiziha metnllov i metallovedoniye, v, 13, no. 3. 1962, 436 - 44o TM-i It has already been established that the effective- ness of vibration as; a ineans of grain-refining of the structure of castings varied from alloy to alloy. It has been possible in. the case of some materials, to determine the optimum conditions of this treatment; in the case of other (pure zinc and the 18-8 stainless steel. in particular) materials, the treatment seems to be ineffective irrespective of the frequency, amplitud* and intensity of vibrations employed. The-prosent author analymed the relevant experimental evidence and caz~e to the concluaion that the most likely explanation of the different res,)onse- of various metals to vibration is beat explained in corms of the theory according to which the grain-rofinament brought about by the application of vibration to a molten alloy Card 18 3/1-6/6"/013/007/015/023 On the problem of .... E193/E383 during casting is due to the fact that this treatment increases the number of crystal fragments broken away from the solidifying skin, providing additional crystallization nuclei. If this theory is correct, then, all other conditions being equal, the beneficial effect of the vibration should be closely related to the strength of the crystals of a given alloy near its solidus. Using his own experimental results and data obtained by M.N. Bochay (Mechanical propertieft of aluminium-alloys during solidification in relation to the formation of hot-welding cracks (Malthanicheskiy svoystva alyuminiyevylth. aplavov v protsesse kristallizataii, i ikh svy&z') - Dissertation, Moscow, 1958), the present authors constructed a graph, reproduced in Fig- 3, where the VrS ((Y, kg/tiun) of Al-Si alloys near the solidus temperature, the thickness (11, mm) of tho columnar-crystals zone and the average grain size (dj rmi) in ingots cast from a vibrated, tundish are plotted atainst the silicon content of the alloy. It will be seen that the concentration depandenci of these three proportion follows the samecourse. Since x Card,2/4 S/126/62/013/003/015/023 On the problem of .... E193/E383 graphs constructed for Al-Cu alloys and stools showed a similar relationship, it was concluded that the extent of the columnar- crystal zone and the average grain size in metal castings were in fact related to tho strength at tanporatures near the solidus and that this relationship determined the effectiveness of vibration treatment as a means of grain-refining of cast structures.

Baykov, AS USSR, has investigated the use of ultrasonics (US) in the welding (WG) of metals and, more especially, in the submerged automatic electric slag WG of austenitic steels. In WG of XZ5HZO (KhZ5NZO) steel and XZOH80 (KhZON80) alloy the use of US reduces the hot-cracking tendency, probably by disrupting their columnar structure and reducing the grain size. US was introduced into the welding bath: (1) Directly through the wave guide that is rigidly connected to the magnetostriction transformer; (Z) through an extension welding rod slide-fitted into an aperture in the wave guide. Method (1) is suitable for vertical WG and for slag-bath and Thermit WG of rods. Problem: Even a water-cooled Cu wave guide disintegrates soon when in contact with the molten slag bath; on the other hand, a. contact between the wave guide and the solid metal just below the bath is not equally effective. A water-cooled steel wave-guide with a water-cooled copper tip serves best.

Method tZ) is also practicable and effective, but it incurs a special problem i~ the welding-rod feed rate: If the rod feeds too fast, it penetrates deeply into the bath and the US effect Is strong, but the rod does not malt evenly and whole hunks of it are found floating in the bath; if the rod feeds too slowly, it melts before it can attain an appreciable immersion depth in the bath, and the US effect is scant or nonexisting. Hence, the feed rate must be selected for optimal compromise performance. On balance, method (Z) has proved more effective and was employed in the tests in which the effectiveness of US in re- ducing hot-cracking tendency was ascertained. The possibilities inherent in the use, of an US welding rod that is chemically different and electrically insulated from the weldino wire are far-reaching, especially in inhibiting grain growth and intercrystal- line corrosion in austenitic steals, elements that are of great essence in improving their creep behavior. Also ofAnterest is the US welding of chromous ferrite steels with up to Z7% Cr, which are eminently notch- sensitive. regardless of their heat treatment. These steels have a notch toughness at room temperature of some tenths of one kgm and a tendency toward irreversible grain growth. The US work of Ya. V. Gurevich, V. 1. Leontlyev, and 1. 1. Teumin has shown that the notch toughness of the Cr steel X27 (KhZ7) can be increased significantly by reducing the grain size. There are 3 figures; no tables or references. ASSOCIATION: None -given.

Under the action of the vibr-- ations and the liquid metal, this is removed and results in solid fragments being present in the liquid motnl poured into the mould. These become the crystallisation nuclei. The theory was tested by using a pouring channel at 650 0C for aluminium. At this temper- ature no solid metal formed and no refinement occurred. Figs. 4a and 4b show that no change in structure occurred at this temper- ature when vibrations were used. If aluminium wire was fed into the pouring channel, however, grain refinement occurred (Fig. 4c). This confirmed the theory that solid fragments of metal were causing nucleation. In the continuous casting of aluminium and magnesium alloys, it is therefore necessary to use a cooled pouring arrangement to obtain grain refinement by vibrations.

In the casting laboratory of the M%1rU, a pro- cedure was developed for casting through a vibrating chute or funnel (shown In Fig. I of the Enclosure) at 1,000 oscillations per minute. Vibrations of both the mold and the funnel led to finer grain stze because of the disintegratton of the solid phase.

Before pouring the katerial, the mold was covered by hwmchloroethans (C2C3,6) for alumimun alloys and with acetylene carbon black for the ML15 alloy.

The microstructure of the panels showed no observable effects caused by minimum or maximum superheat conditions. Howeverv there was a noticeagle increase in nonuniform porosity for very thin-walled specimens cast from V15 and AL19 alloys, There was considerable scatter in the measured strength of various specimens, caused primarily by a nonuniform temperature distribution in the casting during the pouring of the alloy in the mold. It is shown that the melt temperature distribution In the moldj the method of pouring the melt 'in the mold, and the method of feeding, the alloy during the hardedning process &re'aignificant factors contributing to the nonuniformity between specimens and within the given specimen itself. A detailed comparison is made between casting in aandatone molds and a pressing-out methos to enhance uniform temperature distributions in the molten alloy.

Under the prolonged action of vibration on the malt (in a vibrating mol4), rapid cooling of the overheated malt Is observed. This may be explained by the Intensive malting of the hard crust on the surface. it Is noted that the action of vibration on the molt during cry- stallization can also be produced by other types of external Influences (ultra- sonic treatment$ of malts for casting and welding, periodic variation of speed for centrifugal casting, pouring of large coatings through a cooled shaft, and Induction mixing of the malt during continuous casting).
