Increasing the relaxation resistance of heat resistant Ni−Cr alloys by conditioning

Conclusions 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 practical use (although it is smaller than at 700–725°C). At temperatures up to 850°C conditioning cannot prevent the intensive relaxation weakiening that is characteristic of Ni–Cr alloys at this temperature.Central Scientific-Research Institute of Ferrous Metallurgy.
