Abstract

The effects of replacing Cu or Y by a small-sized B in the Mg₆₅Cu₂₅Y₁₀ based alloy are examined. It is found that the replacement of Y by B consistently leads to apparent degradation in GFA; the large sized Y seems to be irreplaceable. In contrast, the replacement of the small sized Cu by the even smaller B to a small amount (1-5%) appears to be beneficial in terms of wider ΔT, higher GFA, thermal stability, and hardness, as well as lower density. In this study, the optimum quaternary alloy composition is identified to be Mg₆₅Cu₂₂Y₁₀B₃.
