Abstract
Positron annihilation lifetime measurements were made on well calibrated fa tigue samples of SS-304. Measurements were made on a high and low carbon al loy. Two separate lifetimes, indicating two defect site types were resolved in each sample. Significant Lifetime changes are observed to occur early i n the fatigue cycles. (C) 1999 Elsevier Science B.V.
