Abstract
Low-cycle fatigue life for various kinds of high temperature materials has been analyzed by a modified Larson-Miller parameter. written by P = T (logN25 - Alog epsilon + B), where T is temperature, N25 is fatig ue life under symmetrical strain wave shapes. Epsilon is strain rate, and A and B are constants. Test data used in the analysis are from NRI M Fatigue Data Sheets of popular engineering materials of nine kinds. ten heats including carbonsteel to Fe-base super alloy. The results ha ve been compared between the materials and compared with statistical a nalysis results adopted in a design code.
