Structure and properties of alloys of the Ni-Cr-Mo system

In the early 1960s the USSR turned to the development of large chemistry. Intensification of existing technological processes and development of new ones with higher temperatures and pressures and more aggressive media required the creation of corrosion-resistant and reliable alloys based on nickel to be used in chemical equipment. At that time the principles of alloying alloys for such composite operating conditions and production technologies had not been formed. This determined the development of scientifically substantiated alloying principles and the creation, on their basis, of corrosion-resistant deformable weldable nickel alloys of different alloying systems (Ni - Mo, Ni - Cr - Mo) with the requisite set of operating and technological properties. Research in this direction led by the author at the Bardin Central Research Institute of Ferrous Metallurgy (TsNIIChERMET) solved the problem.Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 7, pp. 30 – 34, July, 1995.
