摘要：

The effects of hydrogen on ductile fracture were investigated in a spheroidized steel similar to AISI 1520, which contained negligible amounts of P and S. Cylindrical tensile data indicated that hydrogen does not significantly affect void initiation and the early stage of void growth. Instead the effects of hydrogen were observed in the final fracture stages. It was inferred that hydrogen could assist the later stage of void growth by an internal pressure and affect the center crack growth in tension by the enhanced strain localization caused by hydrogen. The fracto-graphic response to hydrogen in spheroidized steels was rationalized by the combination of these two effects, that is, internal pressurization and enhanced strain localization. The critical role of manganese sulfide was manifested by comparison with previous work. © 1990 The Minerals, Metals & Materials Society - ASM International - The Materials Information Society.
