Abstract:

The positron lifetime technique for monitoring changes in material properties is described. Examples of positron lifetime measurements in metals and nonmetals are given. Experiments performed on fatigued and thermally degraded materials indicate that the positron lifetime spectrum is sensitive to these material changes. Author
