Exploration of Trade-Off Between Elastic Modulus and Strength of Mg–Gd–Y–Nd–Zr Alloy by Regulating Intermetallic Phases Through Si Addition

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...
