... this case, there are very few slip bands formed at the lower temperatures because of the in-phase cycle, and damage in this case may be viewed as that which would occur at the highest temperature in the absence of any low-temperature damage. The life for this situation has been computed ( Ref 15 , 16...

... decarburization, manifesting a graphite-free near-surface region or rim. This can lead to increased tool wear and vibrations during surface machining. Extreme degrees of such decarburization can involve a ferritic rim, which reduces machining tool life by fostering a built-up edge. Casting practice-related...

... either a deterministic or probabilistic framework. Fatigue is perhaps the most widely encountered damage mechanism ( Ref 18 ), and two major design philosophies have been employed: safe-life (based on either stress versus life-cycle or strain versus life-cycle curves, Ref 19 ) and damage tolerant (based...
