摘　　要：Thinning procedures were observed by TEM in 310 stainless steel and pure aluminum. Foils thinned through shearing of mode III crack or through tearing of mode I crack. Using micro-beam electron diffraction, the strains in the areas right ahead of crack tips of pure aluminum and TiAl alloy were measured to be 0.05 or more.

关 键 词：THINNING MICRO-BEAM DIFFRACTION strain.
