通过改变退火温度，研究了Zr 0. 5 Be合金的显微组织和力学性能的演变。X射线衍射结果表明，经600 ~ 850 °C退火后，Zr合金由α相和Be 2 Zr化合物组成。光学显微镜和透射电子显微镜的结果表明，随着退火温度的升高，α相的再结晶体积分数逐渐增加。合金的力学性能也通过不同的退火温度进行了研究。结果表明，随着退火温度的升高，Zr0.5Be合金的抗拉强度和显微硬度逐渐降低，而断裂伸长率随着退火温度的升高而增加。位错密度的降低、α相再结晶体积分数的增加以及化合物的分布是导致合金抗拉强度和显微硬度降低、塑性提高的主要原因。这项工作提供了一个更好的理解锆合金的机械性能，并有助于铺平道路，为他们的进一步发展。
The evolution of microstructure and mechanical properties of Zr0.5Be alloy were investigated by varying the annealing temperature. X-ray diffraction results show that the examined Zr alloy is composed of α phase and Be2Zr compound after annealing at temperatures between 600 and 850 °C. The optical and transmission electron microscopy results reveal that the recrystallization volume fraction of the α phase gradually increases with increase in annealing temperature. The mechanical properties of the alloy were also investigated by varying the annealing temperature. It was observed that both the tensile strength and micro-hardness of Zr0.5Be alloy gradually decrease with increase in annealing temperature, while the elongation-to-failure increases at higher annealing temperatures. The decrease in dislocation density, the increase in recrystallization volume fraction of the α phase, and distribution of compounds were largely responsible for the decreased tensile strength and micro-hardness and improved ductility of the examined alloys. This work provides a better understanding of the mechanical properties of Zr alloys and helps pave the path for their further development.
