S/129/62/000/002/On/w4 ApplLcaLlon of steel EJL93/E383 (precipitation of Ni3Ti at the grain-boundary regions and in the interior of the grains) and in a decrease in the lattice parameter. The results of the next series of experiments showed that the hardness of the steel studied decreasedon 0 heating, reaching a minimum of approximately 160 HB at 600 C, then increasing to a maximum of about 210 at 8oo 0C and decreasing on further heating to reach the value of - 50 at 1. 0000C~, the final decrease in hardness was attributed to coalescence of the hardening-phase particles and softening of the solid-solution matrix. Since the preliminary ageing treat- ment, recommended for parts operating at 680 - 750 C, was 16 hours ageing at 750 0C, parts operating at 800 0C would have to be aged at, say, 850 OC and the effect of both of these treatments on the creep properties of steel E1692 was studied in the next series of experiments.2 The results are reproduced in Fig. 2, where the stress (kg/mm ) is plotted against time-tow- rupture (hours) at 800 OC, Curves 1 and 2 relating to specimens Card 2/5 S/129/62/000/002/011/014 Application of steel .... E193/R383 preliminarily austenized at 1 150 0C (2 hours at the tempering temperature followed by air-cooling) and0aged for 16 hours at 750 OC (Curve 1) or for 20 hours at 850 C (Curve 2). It will be seen that although in the high applied stress (12 - 24 kg/mm2) range the0resistance-to-creep of specimens preliminaril9 aged at 750 C was higher than that of material aged at 800 C, this difference practically disappeared in the low-stress (i.e. long time-to-rupture) range. Since no anomalous changes in the elastic modulus or heat-conductivity 0 were observed in the steel studied when heated from 700 - 800 C, it was concluded that this steel retained its high thermal stability at 8oo 0C and could be recommended for use at this temperature.

The strength and ductility were determined at 20, 35o, 6~O and 750 OC; the yield point was determined by measuring the deformation by means of an instrument with a scale division of 0.02 mm. Conclusions: weld seams on the steel Khl8Nl2'Lkl2T, produced by means of automatic tube-welding equipment with non-melting electrodes in an argon atmosphere, have the same strengtiv as the base metal.

TITLEt Effect of nio�ium on compolattion of borides in high-boron steels SOURCEt Fiziks meta4ov i metallovedeniye, v. 18, no. 1, 1964, 153-1 155 TOPIC TAGSt high boron steel, high boron steel property, niobium boron steel, boron nLobium steel# niobium boron steel property, nLo-! bium boride ABSTRACTt High-boron steels containing more than 0.2% boron have low ductility and poor forgeability owing to the presence of a low- melting and brittle boride phase, which solidifiec between dendrites. Hot pressure working and heat treatment can change the structure and' mode of distribution of this phase, but they do not improve the duc- tility. Iron and chromium form primarily lower borides of the Me2B type whose specific weight does not exceed 6.5-&/cm2. Thus, in a low- carbon steel alloyed with lZ boron, the content of the boride phase Cord- 1/ 3 ACCESSION NR: AP4042813 is 12% by weight and 14% by volume. The notch toughness of this steel does not exceed 2 kgm/CM2. An attempt has been made to reduce the volume and hence the detrimental effect of the boride phase by additional alloying of high-boron steel with niobium, which forms ' primarily higher borides of the HeB2 typee Tests were made on three low-carbon steels? designated 1,2, and 3, with respective contents of 0.03, 0.03# and 0.06% carbon, 2.16, 1.56, and 0.942 boron, and 0.7, i 1,38, and 1.22% niobium. It was found that with an increasing nio- bium:boron ratio,the content of the boride phase dropped from 24.2 weight% in steel 1 to 9.0 weight%. in steel 3. Simultaneously, the: iron content in the boride phase dropped from 64*5% in steel I to 1 75.5% in steel 3; the niobium content in the boride phase rose from.', 2.1% in steel 1 to 7.OX in steel 3. It can therefore be expected that alloying with nLobLum will have a beneficial effect on the duc-i tility and forgeability of high-boron steels. Origo art@ has three tables.

The survey was conducted over 3. 5 days. It was found that 53 control and 324 indication sendings were transmitted per hour on the average.

For that reason, speeding up the signaling is not a dire necessity. A high-speed centralized traffic control system will be particularly efficient if the Jhn~-~ utilized in a nonuniform manner and at the moments of train crossing W. here the blocks are identical. The following conclusions are offered: Card Z13 SOV/112-57-5-iO9.29 On the Problem of Utilizing Dispatcher's Traffic Control Lines Serving Single- (1) a centralized t,raffic control system for a single-track section having a block nonidentity factor of 0. 6-0.7 should be designed on the basis of a 5011/0 code-line utilization; (2) with a nonidentity factor over 0. 7, all the more for the sections with identical blocks, the 50% basis of line utilization does not exclude considerable overcrowding of the line at some moments; in such ca~~k,,S, a high-speed centralized traffic control system should be used because it cut.:; line overcrowding and makes an Increased number of units possible. 4 illustrations.

Abstract: of Seailles, by gypsum or by anhydride in order to obtain, on clinkering, in addition to soluble Ca aluminate, gases containing SO 2* Semi-production scale experiments, carried out in an industrial furnace, demonstrated the possibility of a con- current production of H2 SO from gypsum and of Al 03' by clinkering of a Aixture of gypsum, bau- xi~e and coke, with the formation of soluble Ca aluminates. The resulting gases contained 8-11% SO 29 which permits their utilization for the production of H2SO4 , and also for sulfitization of cellulose.
