Crack growth and CREEP-fatigue interaction behavior of 2 1/4 Cr--1 Mo steel

Conference ·
OSTI ID:4140148
Cyclic strain-controlled fatigue tests and cyclic tension-tension crack growth tests employing precracked specimens are being conducted at RT to 593$sup 0$C in various environments including air, steam, vacuum, and impure He. Fatigue and creep-fatigue data at 482 and 538$sup 0$C, effects of temperature, waveform, and hold time or strain rate of fatigue life; comparisons with linear damage rule; subcritical crack growth tests; effects of variation of min to max load ratio; and effects of environment (air, steam, He) on crack growth are given. 15 figures.
