摘要：

This paper reports a detailed electron microscope study of slip occurring at the fatigue crack tips for an intermetallic fully lamellar TiAl alloy. The formation mechanism of the slip bands, their nature and constitution and the relationship between the slip bands and microcracking have been suggested. (C) 2001 Acta Materialia Inc.
