. It was shown that brittle inclusions with large sizes above 30 μm prompted the occurrence of subsurface crack initiation and the reduction in fatigue strength. The fracture toughness and the stress...Effect of inclusion size on the high cycle fatigue strength and failure mode of a high V alloyed powder metallurgy tool steelJun Yao, Xuan-hui Qu, Xin-bo He, and Lin Zhang State Key Laboratory......
Fracture Loci in Sheet Metal Forming: A ReviewM.Beatriz Silva1,Kerim Isik2,A.Erman Tekkaya2,Paulo A.F.Martins11. IDMEC, Instituto Superior Técnico, Universidade de Lisboa2. Institute of Forming Technology and Lightweight Construction, Technical University of Dortmund摘 要:Fracture in sheet metal forming usually occurs as ductile fracture, rarely......
fabricated using gas tungsten arc welding (GTAW), electron beam welding (EBW) and friction stir welding (FSW) processes. The effects of three welding processes on the tensile, fatigue and corrosion behaviour were studied. Microstructure analysis was carried out using optical and electron microscopes. The results show that the FSW joints exhibit superior tensile and fatigue properties compared to EBW......

, Anhui Key Lab of Materials Science and Processing , Anhui University of Technology摘 要:Low cycle fatigue behavior of a quenched and tempered high-strength steel(Q960 E) was studied in the strain amplitude ranging from ± 0.5% to ± 1.2% at room temperature. As a result of fatigue loading, the dislocation structural evolution and fracture mechanism were......
Effect of RE Modification and Heat Treatment on Impact Fatigue Property of a Wear Resistant White Cast Iron 常立民1,刘建华2,王继东1,张瑞军2 (1.Analysis and Measure Center,Jilin Normal University,Siping... of fatigue cracks in a wear resistant white cast iron after impact fatigue test were observed by means of optical microscope and SEM, and the relationship among the content of RE (rare earths) in the wear......
