快速凝固Al-Ti合金的再结晶 吴进明1,叶仲屏2,李志章1 (1.浙江大学材料系,杭州,310027;2.浙江省经济建设规划院,杭州,310012) 摘要:本文研究了快速凝固Al-Ti合金的再结晶行为,探讨了增强相Al3Ti颗粒对合金再结晶进程的影响.结果发现,颗粒体积分数为0.001~0.14,颗粒半径为0.8~1.3μm的Al-Ti合金的再结晶温度为310~350℃,再结晶激活能为41.7~93.0KJ/mol.增强体Al3Ti的存在促进再结晶晶粒形核,增大再结晶驱动力,从而降低再结晶激活能,加速Al-Ti合金再结晶的进程. 关键词:Al-Ti合金; 快速凝固; 再结晶; [全文内容正在添加中] ......
Al-Ti合金电镀镀层的耐蚀性 郭乃名1,过家驹2,魏振强2 (1.中国科学院化工冶金研究所,北京100080;2.北京科技大学,北京100083) 摘要:研究了不同含钛量的Al-Ti合金电镀镀层在0.5 mol/L H2SO4, 0.1% NaCl, 3.5% NaCl水溶液中的耐蚀性能, 800℃抗高温氧化性能以及300℃, 5% SO2气氛下的抗硫化性能, 并测定了镀层的硬度. Al-Ti合金镀层在稀H2SO4及含Cl-的溶液中具有优良的耐蚀性能以及具有良好的抗高温氧化性能及耐硫化性能. 增加镀层中的含钛量, 则可进一步提高Al-Ti合金镀层的耐蚀性. 关键词:Al-Ti合金; 腐蚀; 电镀; [全文内容正在添加中] ......
