为了改善Al在Cu基体中的原位氧化动力学条件,采用Cr代替Al原位氧化制备Cu/Cr2 O3复合材料,采用机械活化后不同溶解度的Cu-Cr粉末制备Cu/Cr2 O3复合材料,并对其显微结构和稳定性进行分析。结果表明,尽管Cu-Cr粉末受到相同的机械活化,但不同溶解度的粉末形成的Cr2 O3颗粒在尺寸、数量和分布上有很大差异。在本实验范围内,Cu Cr粉固溶量为67%时,Cu/Cr2 O3复合材料中Cr2 O3颗粒均匀分布在基体中,具有最好的高温稳定性。
In order to improve the in situ oxidation kinetic condition of Al in copper matrix, Cr, instead of Al was in situ oxidized to form Cu/Cr 2 O 3 composites in the present investigation, Cu-Cr powders with different solubilities after mechanical activation were utilized to synthesize Cu/Cr 2 O 3 composites, and their microstructure and stability were analyzed. The results show that although the Cu-Cr powders suffer from the same mechanical activation, Cr 2 O 3 particles formed by the powders with different solubilities have great differences in size, amount, and distribution. In the range of experiments conducted, the Cu/Cr 2 O 3 composite formed by Cu-Cr powders with 67% solution has large amounts of finer Cr 2 O 3 particles uniformly distributed in the copper matrix and exhibited the best stability at elevated temperatures.
