摘要

The fatigue-crack propagation behavior of heat-treated 4340 steel has been studied as a function of tempering temperature from 400 to 800 F and at +80 and -50 F test temperatures. Fracture mechanics analysis of the data was used for through-thickness cracks in center-notched sheet specimens. Special emphasis was placed on the phenomenon of tempered martensite embrittlement, which occurs in the 500 to 700 F range of tempering temperatures, to see if it can be detected by fatigue testing.
