Mechanical behavior of Alloy 800 at 838 K
Wendell B. Jones,Robert M. Allen +1 more
TL;DR: In this paper, three commercial heats of Alloy 800 have been tested at 838 K in simple tension and in fatigue at constant plastic strain ranges from 0.2 pct. to 1.4 pct, and it was found that significant additional precipitation occurred during the fatigue testing of two of the heats, and this was correlated with secondary hardening behavior found during the mechanical tests.
