Abstract
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.
