摘要
通过OM和SEM研究了锻造温度对TC11钛合金的组织和性能的影响规律。结果表明,随着锻造温度的增加,TC11钛合金中α形态从等轴状过渡到短条状,其抗拉强度和屈服强度随锻造温度的增加而上升,断面收缩率和伸长率逐渐下降;而断裂韧性随锻造温度的增加而提高。
The effects of forging temperature on microstructure and mechanical properties of TC 11 titanium alloy were investigated by means of OM and SEM. The results show that： with the increase of forging temperature, the morphology of α phase of TC11 titanium alloy changes from equiaxial shapes to short strip structure gradually, and the tensile strength and yield strength of TC11 titanium alloy increase with increasing forging temperature; the elongation after fracture and reduction of section decrease gradually; as well as, the fracture toughness of TC11 titanium alloy increases with increasing forging temperature.
