The formation of PSMs and their evolution during cycling was followed. PSMs consist primarily of extrusions accompanied later by parallel intrusions. The kinetics of the early extrusion growth was assessed. At the lowest temperatures only static extrusions and intrusions were found. The findings were discussed in relation to point defect models of fatigue crack initiation.
