The defect structure and microhardness of alpha-Fe irradiated by a hig
h-power pulsed beam have been studied using positron annihilation, tra
nsmission electron spectroscopy, and a nanoindenter, and results are p
resented. It is shown that in alpha-Fe exposed to a high-power pulsed
beam, the pressure gradient and depth of formation of the shock wave f
ront influence the formation and location of the dislocation density m
aximum and the microhardness maximum in the modified layer. (C) 1998 A
