Abstract
The role of grain boundary processes during fatigue testing at high temperatures has been studied in several pure metals. This paper summarizes grain boundary behavior in Al- 3% Mg and Pb- 2% Sn solid solution alloys deformed in fatigue at high temperatures. It is shown that there are significant differences in the processes occuring at grain boundaries in these alloys compared to those observed in pure metals. The implications of these observations in influencing high temperature fatigue fracture are discussed.
