THE CONTRIBUTION TO THE PROBLEM OF THE EFFECT OF PRESSWORKING UPON THE STRESS-RUPTURE CHARACTERISTICS AND DUCTILITY OF ALLOYS

Abstract

A brief review of the influence of plastic deformation upon certain properties of metals and alloys in high-temperature ranges, and the results of an investigation of an Ni-based alloy are presented. The heat-resistant properties of deformed alloys not subject to heat treatment di inish and achieve minimal values when upset more than 45%. Heat treatment of a deformed alloy when the degree of deformation exceeds 70%, may, in some cases, sharply increase the time to failure. With medium degrees of n alloy deformed to the same degree but not subject to heat treatment. Heat treatment of an alloy in the cast condition results in a substantial rise in the maximum indices of stre s-rupture strength as compared to that of cast alloy not subjected to heat treatment.
