Metallureyi i gornoye delo,, no. 3, 1963, 123-126 TOPIC TAGS: - hot rolling, vacuum, inert atmosphere, argon, iron, titanium, molybdenum, n i o b i u m, friction co!fficient, temperature dependence, scale formation ABSTRACT: The temperature dependence of the friction coefficii~nt in the hot rolling of ironJ, titanium, molybdenum, and niobiimi under different conditions has been studied. Specimens were roll!d at a coastant. speed of 6 m/min at a temperature varying from 800 to 1200C In a vacuun, in an argon atmosphere (0-005% 02, 0.01% N), or in We air. 'Pest results showed that with rolling in air the friction coefficient/ror iron, which is about 0.38 at 800C, increases to a maxinnm of 0.45 at 900C and then iecreases gradually to 0.22 at 1200C. 'Card 1/3 L 12937-63 ACCESSION RR: AP3002391 The initial. increase is explained by the decreasing resistance of iron to de-1 formation, and the subsequent decrease, by the effect of iron scale, which softens appreciably above 1000C and a--ts as a lubricant. The friction coef- ficient of titanium increases slightly as temperature increases from 8W to 900C, probably owing to some peculiarLties of the a-to-13-transformation. In- creasing the temperature to 1200C increases the friction coefficient, probably because of decreasing specific pressure. Titanium scale does not soften in the temperature range investigated and hence does not act as a lubricant but rather increases the friction. The increase in the friction coefficient of molybdenum rolled in air, from about 0.35 at 1000C to 0.45 at 1200C, is Isrobably caused by the increasing surface roughness associated with the increasing rliati2ity of molybdenum oxides and the consequent :3urface cleanliness. The friction coef- ficient of niobium in air drops from 0.42 at 1000C at 0.37 at 1250C, owing to the action of the scale which, in thia temperature range, spreads on the metal and forms a dense, smooth surface. The effect of the scale on the relationship of the rolling tem;?erature and friction coefficient is confirmed by the data on rolling in vacuumItW in argon (the latter corresponds roughly to a vacuum. of 0.1 mm Hg). As atmospheric pressure decreases from 760 to 0.00001 = Hg, the friction coefficient of titanium decreases, while those of iron, molybdenumyand Card 2/3 L 12937-63'- ACCESSION NR: AP3002391 niobium increase. The changing conditions of,contact friction should thus be Ia taken Into account in developing the technology of the hot rolling of refractory metals in vacuum or an inert atmosphere.

Values are presented for the coefficients of linear suA ther- mal expansion of wrought Ti in the temperature range 400-1100C. The kinetics of. the sintering process were also studied.

Thepkesshtpaper considers the results of a study of the kinetics of o7ddation of-several T1 alloys under conditions of plastic deformation. The most precise method of testing Is the continuolm J.- weighing process. However, intermediate uamples cannot be taken. Therdore, separate samples were taken for each testing temperature. The samples (10-16 ~ mm cubes). were placed in porcelain crucibles with access to air ensured from all sides and heated to 8W Card 1/6 L 16589-65 ACCESSION NR: AT4048061 1200C (every 100C) for durations of 15,,30, 60 120 and 240 minutes. The samples were then weighed both with and without the crui-iffiles an&with the scale removed. The change in weight was related to sample area prior to oxidation. Fig. 1 of the Enclosure illus- trates the kinetic curves of oxidation of the tested Ti alloys. The tests showed that the oxidation rate depends on the oxygen concejArati6n.gradient in the surface layer of the metal. The value of the oxidation rate was determined by grapblo differentiation of the kinetic curves for prolonged oiddation. Generally, the rate changes graduall and reaches, a constant, known as the characteristic rate. This rate changed from 0. 17 for VT-1 at 800C to 12. 00 at 1200C, from 0. 03 for OT4-1 at 800C to 16. 00 at 1200C, from 0. 33 for OT4 at 800C to 18. 00 at 1200C, from 0. 10 for VT6 at 800C to 13. 00 at 1200C, and from 0. 10 for VT14 at 800C to 10. 25 at 1?,,)OC.

The alloys were roU ad at a rate of 0. 5 m/sec followed by cooling either In water, asbestos or air. The CODling rate as measured by thermoomples was 60-70 deesec in water, 4.3-5 deg/see irt asbestos and 6-6.5 deg/see in air for the VT14 alloy. Mechanical properties were then determined. The tests showed differences In Card 1/3 L 15665-65 ACCESSION NR: AT4048081 hardness of VT14 alloy samples cooled Under different conditions. A11,1119yo showed slight variations in hardness when cooled. from 500460C with 20% compression under the roller. Hardness was Increased significantly by 40% compression and lowering of the temperature from 800C. The effect of cooling rate on strength was noticeable only at rolling temperatures above 900C. For 20% compression the ultimate strength changed smoothly as the rolling temperature variod. -This was not observed for higher comprvs- sion values, confirming the effect. of plastic deformation on the mechanical properties of the alloy. Relative narrowing was increased with compression at all rolling tempera- tures and cooling rates, while the temperature relationship was constant with a- m-inimum at 1000C and maximum at 700C. ElongsUon was lowered during roiling at-temperatares below $OOC with maximum elongation at moderate cooling rates beginning with 1100C. I'he data obtained make it possible to plan methods for Improving the mechanical properties of. titanium alloys by therman.echanical working. However, the thermal stability of the alloys after working will be low and the alloyswill be used successfully only at normal temperatures. Additiona:t research Is required to find ways of employing titanium alloys at higher temperauwes. - "Ye. G. Konstantinoy took part In the investigations.

Type OWIF VT6, VT14 and VT15 alloys were selected; after being heated uniformly for 15-36 nlibutes". depending on the temperature of the ro)ls, the samples were rolled with an average cm- pression of 20,40 and 60% (with similar initial depth ard variable final depth) at 500-1100C. (every 100C). The tests showed that at rolling temperatures above 9000 the specific Card 1/3 L 34518-6.5 ACCESSION NR: AT4048082 pressure was relatively lo*.~ Only ilie VTIS'alloy at a rolling temperature -of 1166C compression of 20% had a specific Vressure of about 9 kg/mM2. . The specific pressure increased more rapidly for the tested alloys than with technical titanium when the temperature dropped from 1100 to 900C. As the compression increased, the specific pressure increased due to friction. Lowering of specific pressure as the degree of deformation rises may be explained by crack formation in the metal due to unequal defor- mation because of the stressed condition In the narrow strips. This leads to higher lateral deformation in comparison wl::th longitudinal deformation. The OT4, VT6, VTIA and VT15 alloys showed a lower plasticity than the VT1 alloy, the VT15 alloy having the lowest. The strips were widened by motion of the lateral surfaces onto the contact surface, although widening was also i. e contact ace, which aused by slipping along th surf was insignificant. Maximum widening at 20, 40 and 60% compression was obtained with M and VT15 alloys and at 900C with VT6 and VT14 alloys at 800C. As the degree of do- formation increased, the widening rose for all alloys.

HTMT increased alloy strength without affecting ductility. For example, prior tc aging ta. tensile strength of alloy hot rolled at 950C with a reduction of 20, 400 60, and BOX was ~6.3, 105.0, 96.7, and 99.5 kg/mm2, respectively, compared with 77.3 kg/mm2 for alloy quenched fr the same temperature without deformation.

ABSTRACT- A detaiied account is g.ven of the thoroughly conducted tests, within the range of non-elastic deformations, of large models (half- to full- scale) of low-alloy steel NL2 (also, S. Kh. L. 2) widely employed in the building of bridges. Compressive and tensile tests of standard samples showed that the proportional elastic limit the yield points,and relative elongation were within the limits of GOST specifications. Compression tests of 11-shaped models were performed on the 500-ton press with special test rigs that ensured good centering of the load and hinged suppo:-ts. The critical load P* was determined with the aid of the stress- strain diagram, namely, as that load at Card 1/2 which tin increase in stra.n is obtained without any increa~Te in stress. 124-11-13411 The Stability of Compression Elements Made of NLZ Steel. (Continued) For models requiring P* > 500 tons, eccentric loads were used and P* computed according tc Southwell's method (ref. Timoshenko, S. P., "The Stability of Elastic Systems", 1955, p. 191). The tests showed that tie critical stress for slenderness ratio of from 40 to 100 is not less than those specified by the TYPM-47 standards. The phenomer.on of buckling failure was not observed. I.

Moscow, Gosstroyizdat, 1962. 57 - 77 T IA T In the design calculations of -aluminium-alloy structures it is usual to assume that the pertinent mechanical properties of the alloys when in tension and corrpress'dn are similar. The object of the present investigation was to check the validity of this assumption, to provide accurate data on some more important prop- erties such as the limit of propor-.-.ionality and the yield- point and to establish the degree of unif'ormity of various semifinished, w,rought products in respect of their mechanical properties. To this end, a large number of tensile and compressive stress/strain (Iiagrams were obtained for the alloys studied. The' Card 1/ 3 S/839/62/000/000/003/004 A study of the ....
