利用自行研制的激光悬浮区熔设备制备了Al2O3/YAG/ZrO2 三元过共晶自生复合材料. 在过共晶成分下获得了不含初生相的全共晶层片状组织.详细分析了固/液界面形貌形成原因, 并由界面形貌出发阐述了Al2O3/YAG/ZrO2 三元过共晶组织织构化趋势.结果表明, 低凝固速率下, 三元过共晶成分下层片间距大于三元共晶成分下层片间距,而在高凝固速率下则相反, 这主要是由于ZrO2的加入影响了体系的...

利用TEM研究弥散Al2O3粒子对变形Cu-Al2O3弥散强化铜合金高温退火显微组织的影响。结果表明:弥散强化铜合金等时(1 h)退火时,显微硬度HV呈缓慢下降趋势,没有发生突降现象;弥散铜高温退火主要以位错亚结构回复为主,而亚晶较为少见;粒子弥散参数和胞壁性质对退火时的回复产生非常重要的影响;Al2O3弥散粒子影响位错在胞壁内的运动,阻碍胞壁内位错重排、迁移,使得胞壁很难通过运动而获得位向差的积...
