摘要
采用搅拌摩擦加工(FSP)技术制备了Al-Ti、Al-Ni两种体系金属间化合物,并对制备温度进行了研究。结果表明:在FSP制备不同体系化合物过程中,随着FSP道次的增加,FSP区域温度不断增加。Al-Ti系的制备温度较Al-Ni系高,搅拌棒与生成产物剧烈摩擦产热程度也远远大于后者。FSP温度远低于材料熔点,属材料固态制备技术,热源主要来源于搅拌棒与原材料的摩擦产热、搅拌棒与生成金属间化合物的摩擦产热及材料间的放热反应。
Al-Ti and Al-Ni intermetallic compounds were fabricated by friction stir process（FSP）,and the preparation temperature was studied.The results show that the temperature in region of FSP increases with the increase of processing pass during the preparation of different alloy systems.The preparation temperature of Ti-Al system is higher than Ni-Al system.The heat produced by friction between stirring rod and product is far greater than the latter.FSP temperature is lower than material melting point,which is a solid multifunctional metal working method.The heat mainly comes from the frictional heat of stir bar and raw materials,intermetallic compounds and exothermic reaction between raw materials.
