Abstract null null The fatigue crack propagation behavior of rolled magnesium alloys was studied and compared with as-cast alloys to unravel a relation between the early crack propagation and the fatigue resistance at the microstructural level. Grain structures results indicated that the geometric compatibility of grains and stress component on basal slip planes determine the propagation path of cracks. Twins are usually unfavorable for crack propagation, and the texture changes the stress compo...

Abstract Low-cost Si was added to Mg-8Gd-4Y-1Nd alloys to improve their ductility. With the Si increased from 0 to 1.0 wt. %, the elongation increased from 8.7 % to 17.1 % for as-extruded Mg-8Gd-4Y-1Nd alloys. Microstructures results indicated that the formation of GdSi and Y5Si3 intermetallic phases increased significantly with the Si addition, which was shown to promote the random orientation of grain structures. As Si works as substitutional atoms in Mg alloys can decrease the first intrinsic...

In this study, low-cost Si was added to an Mg–8Gd–4Y–1Nd–0.5Zr alloy to regulate the intermetallic phases. The mechanical properties of 0, 0.5, and 1.0 wt% Si-added alloys were studied to explore the trade-off between the elastic modulus and strength. The microstructures were characterized through metallographic microscopy, scanning electron microscopy applying energy dispersive spectroscopy, and transmission electron microscopy. The microstructures demonstrated that Y5Si3 and GdSi phases formed...

Abstract The influence of grain size and crystal orientation on the corrosion behavior of as-extruded Mg-6Gd-2Y-0.2Zr alloy is investigated by scanning electron microscopy (SEM), electron backscatter diffraction (EBSD). The EBSD system is used to characterize the grain size, crystal orientation and corroded surface. By investigating the corrosion process of as-extruded Mg-6Gd-2Y-0.2 Zr alloy, we can observe that the smaller grains and (10-10)/(11-20) non-basal planes are more susceptible to corr...
