    Abstract
  • High-current pulsed electron beam (HCPEB) technique was used to irradiate the AISI 304L austenitic stainless steel. The vacancy defect clusters of the irradiated surface layer were investigated by using transmission electron microscopy. The experimental results indicated that a large number of supersaturation vacancies involving vacancy dislocation loops and stacking fault tetrahedra (SFT) were induced on the irradiated surface layer after HCPEB irradiation. Additionally, surface morphologies of the irradiated samples were characterized by optical microscope, scanning electron microscope and non-contact optical profiler in detail. It was found that high density, fine and dispersed micropores were inevitably formed. The dominating formation mechanism of surface micropores should be attributed to the migration of large number of vacancies (clusters) defect along line and (or) surface structure defects towards the irradiated near-surface layer during HCPEB bombardment and cause vacancies accumulation. The present results indicate that HCPEB technique is a new method to successfully fabricate the surface porous metallic materials by selecting appropriate materials and adjusting HCPEB process parameters.
