Abstract:

Modern machines, as well as their indivModern machines, as well as their individual assemblies and parts, perform under conditions of high speeds, temperatures, and pressures. In consideration of these conditions it is necessary to insure the total structural strength and, in particular, the contact strength as well as the wear-resistance of contacting machine parts. The method of testing high-strength steels by the nonuniform volume compression B. D. Grozins method is simple, inexpensive, and sufficiently reliable for appraising their resistivity to plastic deformations which can arise under the actual stress-temperature conditions. Preliminary testing by the nonuniform volume compression method is recommended in assigning the steel of a new brand by comparison withting the rational mode of its thermal processing in the production of such machine parts as pendulum bearings, various kinds of gear wheels, and camshaft lobes. The testing temperature should approximate the temperature at which the part will operate. Author
