摘要
研究了强韧化热处理对ZQA l9-4铝铁青铜组织性能的影响,结果表明,经优化热处理的ZQA l9-4铝铁青铜,强度提高了60%,硬度提高了1倍,同时材料仍有良好的塑性和韧性,从而提高了产品的使用寿命。
The effects of heat-treatment toughening on the microstructure and performance of ZQAl9-4 Al-Fe bronze were investigated. Results show that the strength and hardness of ZQAl9-4 Al-Fe bronze was raised 60% and 1 times respectively, by optimized heat-treatment. Meanwhile the materials still possessed better plasticity and toughness. Therefore the service life of production was enhanced.
