摘要/Abstract

摘要： 研究了纳米TiC对Al-Cu合金铸态、轧态和热处理态微观组织和对热处理态力学性能的影响。结果表明,加入适量的纳米TiC颗粒,可以有效细化合金的微观组织。当TiC含量较小时,随着TiC含量的增加,合金在轧制变形过程中发生了动态再结晶,平均晶粒尺寸减小。当TiC含量超过0.5%(质量分数,下同)时,再结晶晶粒又逐渐长大粗化。当纳米TiC含量为0.5%时,合金的综合性能最优,与基体相比,抗拉强度和伸长率分别提升了约18.6%和7%。TiC/Al-Cu合金在热处理过程中产生了析出相和大量位错,这有助于提高材料的力学性能。

Abstract: Effects of nano-sized TiC particles on the microstructure of the Al-Cu alloy at as-cast, as-rolled, and heat-treated states and on the mechanical properties after heat treatment were studied. The results show that the microstructure of the alloy can be effectively refined by adding appropriate nano-TiC particles. When the TiC content is small, with the increase of TiC content, the alloy undergoes dynamic recrystallization during rolling deformation, and the average grain size decreases. When the TiC content exceeds 0.5% (mass fraction), the recrystallized grains gradually grow and coarsen. When the content of nano-TiC is 0.5%, the comprehensive properties of the alloy are the best. Compared with the matrix, the tensile strength and elongation increase by 18.6% and 7% respectively. During heat treatment, precipitates and a large number of dislocations are produced in the TiC/Al-Cu alloy, which is helpful to improve the mechanical properties of the material.

Key words: nano-sized TiC, Al-Cu alloy, microstructure, mechanical properties
