Comparative estimation of high-temperature creep and rupture of structural materials

Abstract

The possibility of comparing the rates of creep processes and times to rupture of materials is shown by the example of several structural alloys of different types. The creep equation is written in dimensionless form, which allows one to compare creep processes up to rupture in normalized quantities, to estimate their difference, and, in the case of coincidence of the normalized quantities for some materials under corresponding temperature-load conditions, to model the indicated processes using experimental data for one of these materials.
