Abstract

This article focuses on investigation influence of changes microstructure steel 80P and rate of residual stresses on relaxation resistance after mechanical and thermal treatment. Methods of testing included electron microscopic and X-ray studies steel 80P, as well as experiment on stress relaxation. In the course of science work find dependences of relaxation resistance from material structural stability, obtained after mechanical and thermal treatment with different heating temperature and tensile force.
