Erosion of stainless steel first wall by helium blistering

PDF Version Also Available for Download.

Description

The blister formation and the erosion rates associated with helium blistering in annealed 304 stainless steel were investigated for helium projectiles with energies ranging from 100 keV to 1.5 MeV and for irradiation temperatures ranging from room temperature to 550 deg C. The total dose was varied from 0.l C/cm/sup 2/ to 1.0 C/cm/sup 2/. The results show that the blister size increases with increasing projectile energy. The degree of blistering, and the erosion rates associated with blister rupture and exfoliation are found to be strongly temperature dependent. Maximum erosion rates were observed at irradiation temperature of around ~450 deg ... continued below
