FIELD: machine building.
SUBSTANCE: according to the method sample is hardened and its temperature is increased to temperature of recrystallisation, steady load is applied to the sample resulting in elastic deformation, and when temperature is increased change of elasticity modulus is recorded, zone of elasticity modulus gradient increase is found based on dependence of elasticity modulus change in temperature function, line preceding the beginning of zone of elasticity modulus gradient change is extended, line is extended after the end of zone of elasticity modulus gradient change to cross over with the line preceding zone of elasticity modulus gradient change, and absciss of this point is identified with temperature of recrystallisation beginning.
EFFECT: providing possibility of detecting temperature of recrystallisation beginning.
