China 24(2014) 648-656 High-cycle fatigue behavior of friction stir butt welded 6061 aluminium alloy Hrishikesh DAS, Debayan CHAKRABORTY, Tapan KUMAR PAL Welding... strengths were discussed in terms of the microstructure, crack path behavior and fracture surface. Key words: Al alloy; friction stir welding (FSW); high cycle fatigue; stress ratio (R-ratio); crack......
discontinuous grain boundary α phase gives rise to flexural propagating mode. Key words: titanium alloy; low cycle fatigue; laser melting deposition 1 Introduction TC18 is a high-alloyed α+β titanium..., like TC18 titanium alloy. Low-cycle fatigue (LCF) damage of TC18 aerospace components will occur during service process. Therefore, the study on high-stress, low cycle fatigue behavior of TC18......

damages at high temperatures is investigated. The transformation into martensite is observed for both the long-term creep and fatigue. The magnetic regions are observed in sever deformed area and near crack. Then the formation of magnetic phases is related to the damage. The damage at high temperature can be universally evaluated. Key words:creep; fatigue; high temperature; austenitic stainless......
effect on fatigue life of shot-peened specimens under high cycle loading is investigated. The induced residual stress is measured by using the orbital hole-drilling method. Surface profilometer...Effect of Surface Polishing Treatment on the Fatigue Performance of Shot-Peened Ti–6Al–4V AlloyZ.G.Liu1,T.I.Wong2,W.Huang1,N.Sridhar1,S.J.Wang21.
