A Simplified Hot-Tearing Criterion for Shape Castings Based on Temperature-Field Simulation
Current hot-tearing predictions for shape castings are suitable for well-investigated alloys with complete mechanical property databases, but are not applicable to newly developed alloys. This study proposed a...

Effects of Gd and Zr additions on the microstructures and high-temperature mechanical behavior of Mg–Gd–Y–Zr magnesium alloys in the product form of a large structural casting
The microstructures, high-temperature mechanical properties, and fracture behavior of Mg–Gd–Y–Zr alloy components produced by low-pressure sand casting with different Gd and Zr contents, have been investigated...

High cycle fatigue properties of cast Mg–xNd–0.2Zn–Zr alloys
The tensile and fatigue strength of cast Mg–xNd–0.2Zn–0.45Zr alloys (x = 0, 1, 2, 3 wt%) in both solution-treated (T4) and solution + 200 °C peak-aged (T6-PA) conditions were investigated in the present study. Th...

Grain Refinement of AZ31 Magnesium Alloy by Titanium and Low-Frequency Electromagnetic Casting
The grain-refinement effects of titanium (Ti) additions and a low-frequency electromagnetic casting (LFEC) process on the AZ31 magnesium alloy have been investigated. It is shown that Ti has no effect on the f...
