摘要
The mechanical properties of Mg77.5Zn8.5Y14 (at%) alloys solidified under various pressures were studied to clarify the effect of the solidification pressure and pressure-induced Mg64Zn15Y21 phase on the mechanical properties. The results showed that hardness, compressive properties were greatly improved simultaneously. The presence of Mg64Zn15Y21 phase increased the ultimate strength, but reduced the elongation. The eutectic and Mg64Zn15Y21 phase coexisted uniformly, this composite structure improved mechanical properties significantly. In addition, the mechanical properties were also affected by the pressure-induced solid solubility change, eutectic spacing and microstructure. (c) 2020 Elsevier B.V. All rights reserved.
