摘要

研究了重熔温度对粉末触变成形制备Ti@Al

/2024Al基复合材料组织与力学性能的影响。结果发现

随着重熔温度升高

初生相颗粒逐渐长大

Ti反应层逐渐增厚

材料从最初的缺陷断裂转变为韧性断裂再转变为最后的脆性断裂。当重熔温度为645℃时

合金抗拉强度和伸长率都达到最高

分别为361 MPa和13.7%。

Abstract

Effects of reheating temperature on microstructure and tensile properties of the Ti@Al

Ti/2024 Al matrix composites fabricated by powder thixoforming were investigated.The results indicate that the primaryα-Al particles are coarsened gradually and the reaction shell of Al

Ti is increased with increasing the reheating temperature.The crack mode of the composites is transformed from defect fracture into the ductile fracture and finally into brittle fracture.The results indicate that the composites thixoformed at 645 ℃ have the desirable comprehensive tensile properties

where the ultimate tensile strength and elongation reach 361 MPa and 13.7%

respectively.
