________ is a loss in toughness due to a metallurgical change that can occur in alloys containing a ferrite phase, as a result of exposure in the temperature range 600º F to 1000º F.

Question

Quizplus · Accepted Answer

885º F embrittlement is also known as the sigma phase embrittlement, which is a loss in toughness due to the formation of the sigma phase in certain alloys containing a ferrite phase. This occurs in the temperature range of 600º F to 1000º F, and the sigma phase is known to be brittle and can reduce the ductility and impact strength of the alloy.
