I. Theoretical bases SOURCE: Polska akademia nauk. Bulletin. Serie des sciences techniques, v. 14, no. 6, 1966, 587-595 TOPIC TAGS: detonation wave, compressive stress, pressure effect APSMACT: The authors consider a new method for producing dynamic pressures of tens of millions of atmospheres. The method consists of ccmpression by imploding a thick-1 valled pipe with a core having an outside diameter less than the inside diameter of the pipe. During the first compression phase before the inside diameter of the pipe equals that of the core, the work done by external pressure is transformed into kinetic energy In the second phase the whole system is compressed and the ace"Plu- latcd kinetic ener is simultaneously traiioformed into internal energy. The gredific score in an incompressible pipe is studied. It is assumed that co5c of a graphitey both are n-on-vTs-cous liquids. Expressions are derived for the radial motion of this L 05 2 23 - -6 7 ACC NR: AP6027425 system under the effect of a ocnstant external pressur( po. The density of tile pipe mat-erial is assumed to be constant -,Chile th~it of the internal core depends only on time (is independent of position). It is further assumed that pressure pe is co great (of the order of pressures in a detonation wave front) that the motion of tile material in both elements conforms to the hydrodynamic laws for a nonviscous liquid. The density, internal pressure and -:elocity of the pipe and core elements are deter- mined. The results indicate that the assumptions are not realistic since velocity is independent of time and the moment when motion ceases cannot be determined. The solution indicates that the radius of the core may reach zero so that the whole mass is concentrated at the axis. Actually the shockwave is reflected when it reaches the axis and the following rarefaction wave may fracture the core material as is frequent],y observed in experiments. The concept of homogeneous density must be given up -to bring the results into agreement with experimental data. Orig. art. has: 4 figures, 36 formulas.

A particular case of the necessary and sufficient condi- tions described is that of the stability of a gyroscope with a vertical outer axis. The instability of the system is determined by estimates on cyclical coordinates. The vector of average deviation of the system from unperturbed precession during the time of nearest nutation oscillation is defined. Several examples are offered to show the application of the formulas for stability conditions to specific gyroscope systems. Orig. art.. has: 62 formulas.

Weighed samples Of COS04 and NIS04 were dissolved in pre~- Icisely measured volumes of water, adjusted to the desired pH by the addition of H2SO4 or XaOH and a solution of an oxidizer ( XaClO, KaC102, H202) was added in excess. The reaction mass was brought to 'boiling and immediately passed through a glass filter. Hydroxides :were washed with a hot solution of the same yH-as was the filtrate.

It was found that the separation of nickel from cobalt at 90-1000 using sodium hypoohlorite as oxidizer is achieved at pH 4 1 , and usIng sodium chlorite at a pH of from 2.5 to 3.5. Only hydrogen.peroxide, can be used for quantitative determination of cobalt.

The object of the present invest-igatlon was to study the effect of high service temperatures on the characteristics of springs made of this steel. Hot-rolled rods, 8 and 10 mm in diameter, were cold-drawn to 4-5 mm diameter wire, whose UTS was 145 and 160 kg/mm 2, respectively. These wires were coiled into cylindrical springs, 29 mm internal diameter, 59 mm high I with a pitch of 10 mm. After coiling, the springs were held at 450 OC for 30/~Ln, cooled to room temperature, compressed to complete Card S/129/6i/ooo/on/oWolo Relaxation stability of .... 19193/E383 closure and held for 24 hours at room temperature. After preliminary relaxation, the sprIngs were compressed again in jigs and held at 450 OC for 30 min. After this treatment the load required to produce a certain predetermined compression was measured. The springs were then compressed in jjigs to a height of 32 mm, placed in a furnace at 385 - 420 or 450 OC and heid at the temperature for I to 2 000 hours. The springs were removed from the furnace at regular intervals and the load required to produce compression equal to that obtained in the initial test was determined again. Some of the results are reproduced graphically in a figure, where the compression stress (0~ kg/mm2) is plotted against the duration (hours) of treatment at 385, 420 and 450 OC (graphs a, 6 and B, respectively), Curves 1 and 2 relating to springs made from wire obtained, respectively, from 8 and 10 mm rods. Since there was a possi- bility that these results had been affected by repeated loading and unloading of the springs during the treatment, the tests were repeated on specimens which, after being held at the test temperature for a given time, were tested and not used again.

The effect of time and temperature on hardness of the steel lKhl8NqT is illustrated in Table 2. It is concluded that springs of hardened steel'lXhl8NqT0have sufficient relaxation stability at temperatures up to 385 C, the decrease in o- after 2 500 hours at this temperature ainountinS to 411.51"'l, the corresponding decrease at 450 0C being 88.5910 after 750 hours. only. The relaxation stability is not affected by the degree of vrork- hardening during drawing of the spring wire. A slight increase ci -0 in hardness of the spring material during the first 100 hours of treatment was attributed to the effect of ageing.

TITLEi Methods for testing the fatigue strength of heat resistant ropes at elevated temperature PERIODICALt Zavodskaya laboratoriya, v. 27, no. 5, 1961, 589 - 591 TEXTi A method and a device of simple design are described, which permit an estimate of the fatigue strength of a steel rope till it is destroyed partly or completely, based on the number of bendings over a pulley, for a rated stress and at elevated temperature. In these tests, the number of bendings is recorded by a counter and the temperature of the rope is measured. These tests enable not only the statement of the bendings, but also the investigation of several further factors having a neg'ktive in- fluence upon the fatigue strength of the rope, such as oxidation. A rope was manufactured and tested for 10,000 hours at a temperature of 70000- A load being continuously in a shaft of 70000 is fixed to one end of the rope. The other and of the rope io fixed on a drum. The ropes were manu- faotured of pure molybdonum-ohrome-nickel-tungeten-stoo1 of the type ~W726 i(EI726) and of an alloy on -nickel basis aH893 (EI893) in the Teentrallnyy Card 174 24163 S/032/61/027/005/009/017 Methods for testing the ... B130/B220 nauchno-issledovatel'skiy Institut ohernoy metallur ii (Central Scientific Research Instituteof Iron Metallurgy). The device 7Pig. 1) consists of a frame 1 on which a motor 2 and a reductor 3 with pulley 4 are mounted. A returning rotary motion is transmitted from the pulley of the reduotor to the drum 6 by means of a push rod 5. The rope 7 passes an oven, a pulley 8, and a second oven. k load is fixed to the other &nd, of the rope. The heating of the rope is effected by 2 tube furnaces 10 situated in the neighborhood of the pulley 8. T *he temperature of the oven is measured by a chromel-alumel thermocouple and controlled by means of an hPUP-54 (MRShohPr-54) instrument. The number of bendings of the rope over the pulley is recorded by a Cb-1M/100(SB-1M/100) counter. Since that part of the rcpe which runs over the pulley is not always in the oven, a differ- ence developes between the temperature of the oven and that of this point. The temperature of the rope next to the pulley is measured by means of a thermocouple and via a vibrator recorded by a 30 -4 (E0-4) oscilloscope in a special test under small load, in order to ascertain this difference. There are 4 figures. Card 2/4 314682 S/129/62/000/002/oll/ol4 E193/E383 AUTHORS~ Lupakov.

Metallovedeniye 1 termicheskaya obrabotka metallov, no. 2, 1962, 49 - 51 TEXT-, The object of the present investigation was to check whether the steel E1692 (0-05% C, 0.7% Mn, 0-19% Si, 15.290% Cr. 36-5% Ni, 2-5% W, 2.49% mo, 1.48% Ti, 0-008% S, 0-023% P, 0.02% B (calculated), 0 025% Ce (calculated)$ developed originally for service at 600 - 75; 0C, could be used at 800 OC. To this end, various properties of this steel were studied on specimens which, after a preliminary austenizing treatment (air-cooling from 900 0C) followed by 10 hours ageing at 850 0C, were held at 800 OC for periods of lip to 2 130 hours. Theresults of these experiments are given in Table 1. The variation of the mechanical properties was reflected in the structural changes Carc~ 41/5:
