چکیده انگلیسی
Cyclic deformation and fatigue behaviors of Mg-12%Gd-3%Y-0.5%Zr (wt%, GW123K) alloy were investigated at room temperature under axial cyclic loading in strain controlled condition. It is shown that conventional extruded GW123K alloy maintained cyclic stability at strain amplitudes ranging from 2Â ÃÂ 10â3 to 10â2. The pronounced symmetric hysteresis loops were also observed during cyclic loading. Fracture surface observations indicated that fatigue cracks mainly initiated at large Gd-riched phase or at inclusion clusters at surface or subsurface, and grain boundary (GB) and slip bands (SBs) are also preferential sites for micro-crack incubation.
