Abstract:

The positron annihilation meanlife change caused by defects created by heat treatment or deformation for aluminum, titanium and their alloys and some nickel base superalloys are described. Positron annihilation lifetime measurement can be used as a method to determine certain defects in these metals. The sensitivity and limitations of the method of positron annihilation lifetime measurement are briefly discussed. The direction of possible future research is also described. Author
