Abstract

The strain hardening curves of molybdenum are analysed in the co-ordinates of dσ/dε - σ for the wide interval of temperatures of 20-1000 оС. It is rotined that the rate fixing of speed of strain hardening on the elastic modulus and yield strength and deduction from the size of yield strength stress at the set temperature allows to take all curves of the strain hardening to uniform dependence. Temperature dependence of strain hardening coefficients was analysed.
