In mid-1995 the N. [~. Bauman Moscow State Engineering University celebrated its 165th anniversary. At the beginning of this century the university gave birth to many scientific schools and investigations. among which a central place belonged to the Moscow School of Metallurgy (1909), which determined in many respects the development of materials science, methods of heat treatment of materials, and their use in industry.For 87 years the ideas of metal science have been developed in the Department of Materials Science and Heat Treatment. It has always been a leader in the countrT's research in the field of metallic materials and maintains this position at the present time, which can be inferred from the results in the works presented below.The interests of the Department cover creation of new metallic alloys, investigation of the effect of heat treatment on the structure and properties of structural steels, creation of new methods of physicochemical treatment, investigation of corrosion processes, and many other topics. Austenitic dispersion-hardening alloy 36NKhTYuM8 is well known as a nonmagnetic corrosion-resistant and heat-resistant spring material having quite good technological ductility (after quenching) and a high yield strength after aging (oo 002 = 930 -950 N/ram2). It is used for the production of complicated and critical elastic members. There are data on the possibility of a certain improvement in the adaptability to manufacture and the operating properties of the alloy. The present work concerns the possibility of rapid quenching with the use of electric-contact healing for alloy 36NKhTYuM8.It is known [ I -3] that conventional quenching of alloy 36NKhTYuM8 with heating to 1000-1050°C does not provide complete dissolution of the excess Laves Fe~Mo phase. The particles of this phase retained in the structure of the quenched alloy decrease its technological ductility, prevent full realization of the effect of dispersion hardening in aging, and play the role of stress concentrators that decrease the fatigue strength of the material under cyclic loads. Nevertheless, the alloy is not quenched from a higher temperature due to its susceptibility to grain growth.Under these conditions, it seems expedient to turn to rapid heating for quenching the alloy. In rapid heating combined with short-term holds the alloy can be superheated (above the conventionally used quenching temperatures). which should intensify the diffusion and thus create conditions for dissolution of a larger amount of the excess phase with retention of the fine-grain structure. For thin-sheet and wire semi-finished products of the spring alloy the most efficient method of rapid heating is electric-current contact heating [4]. As applied to dispersion-hardening alloys, this method has been used in [4] for aging and in [5] for rapid recrystallization annealing without selective aging of the alloy in the heating process; in both cases the resulting material had a fine-grain structure.We investigated ~ the effects of the regimes of rapid quenchi...
