The Effects of Metallurgical Variables on the Environmental Fracture of Steels.
Abstract
An analysis has been done on the role of metallurgical variables in controlling the susceptibility of iron alloys and steels towards environmental cracking and embrittlement. The role of individual variables was demonstrated using purified iron as a model system, and then extended to more complex alloys. Specifically, the results indicated that C and Mn degraded performance, while Si improved it. The role of grain texture and heat treatment was examined in detail. The effect of the latter variable was discussed vis a vis the connection between hydrogen and thermal embrittlement. Environmental embrittlement for steels was shown to be compatible with hydrogen control, but the precise mechanism was not established. (Author)
