DISCUSSION ON DEFECTS DISTRIBUTION NEAR THE STEEL SURFACE IRRADIATED BY INTENSE PULSED ION BEAM W.J.Zhao1,B.X.Han1,W.Xiang1,X.Y.Le1,S.Yan1 (1.Institute of Heavy Ion Physics, Peking University... wasdiscussed and analyzed. The defects near the surface of stainless steel were generatedin two ways: (1) generated by the bombardment of energetic ions and (2) induced bythe high level stress near......

="ChDivSummary">Using high aluminum refractory material as substrate at 1 400 ℃, we studied the connections between several oxides such as Fe 2 O 3, MnO 2, CuO, and the formation of defects such as coating crack... show that oxides with low melting point in the penetrating area of the substrate may form eutectic with low melting point and produced thermal defects, which leads to the erosion by penetrating......
:Molecular dynamics simulation of uniaxial tension along [001] has been performed to study the influence of various surface defects on the initiation of plastic... dislocation nucleation site. The defects on surfaces and edges cause further weakening with various effects depending on defect type, size, position and orientation,while the edge dimples are the most......
