| 摘 要： | 采用自蔓延高温合成法 (SHS)制备了 3 0 %TiC/Al中间合金 ,再以 2 0 14铝合金作为基体 ,利用搅拌铸造法加入一定量的中间合金制备 5 %TiC/ 2 0 14铝基复合材料 ,并研究了中间合金中相组成以及TiC颗粒的加入对复合材料力学性能的影响。研究表明 ,采用SHS技术制备的中间合金中只形成尺寸细小、排列紧密的TiC颗粒 ,TiC颗粒的加入可以提高TiC/ 2 0 14复合材料的力学性能 ,尤其是高温性能。

| Abstract: | TiC/Al master alloy prepared by self propagating high temperature synthesis (SHS) technique can be added to 2014 aluminum matrix to fabricate 5%TiC/2014 composite by stir casting. X ray diffraction and SEM were used to examine the phases of master alloy, and microstructure and mechanical properties of 5%TiC/ 2014 composite have been investigated. Results show that TiC particles have remarkable grain refining effect on 2014 alloy and increase the mechanical properties of 2014 alloy, especially at high temperature. |
