Mutual relation in description and analysis of high temperature creep peculiarities for metallic materials

A problem on the necessity to systematize the known data on mechanical properties of high temperature steels and alloys with the aim to increase efficiency for verification of potentialities of the developed state equations is analyzed. One of the variants for description of regularities of the instant and short-term deformation, creep, stress relaxation and long-term strength proceeding from the general positions is substantiated
