High brittleness
Web1 de set. de 2024 · It is found that the underlying mechanism of the high temperature brittleness of Mg-Gd-Y-Ag alloy was induced by segregated compounds (the Mg3 RE and Mg 2 REAg phases) along the grain boundaries. 2. Materials and methods. The composition of Mg-RE alloy was Mg-10Gd-3Y-2Ag in weight percentage (wt. %).
