Abstract : This review report addresses the microstructural and environmental 'short' crack studies that have been conducted since 1965. This includes discussions on present understanding of the mechanisms of 'short' crack behavior of materials, and microstructurally 'short' crack studies including the effects of grain size, grain and phase boundaries, variation of precipitate size, processing technique and stress ratio. In addition, this report discusses environmental influences in the 'short' crack regime. Also, a title list of 'short' crack related works published so far is included.
