The effect of repeated loading (conditioning) in the first period of relaxation on the relaxation resistance of heat resistant Ni−Cr alloys depends on the working temperature. At 750–800°C the effectiveness of this treatment is adequate for prac

Prolonged tests of ring samples at 750°C shows that the relaxation of stress decreases continuously during testing for 20,000 h. Apparently, this decrease is due to the gradual stabilization of the structure of the alloy investigated.
