【摘要】 采用原位反应工艺 ,通过在 Al熔体中加入 Ti O2 ,在一定温度下产生化学反应 ,反应生成 Al3Ti颗粒 ,然后采用搅拌铸造法制备 Al/ Al3Ti复合材料。当 Ti O2 加入量为 2 0 %～ 30 % (质量分数 )、反应温度为 92 0℃时 ,铸态复合材料具有良好的力学性能。更多还原

【Abstract】 Pure aluminum matrix Al 3Ti particle composite was made by a new in situ method involving reactions between Al and TiO 2 is which was stirred into molten metal under the conditions of certain temperatures.When the amount of TiO 2 20%～30% and the reaction temperature is 920℃,the good mechanical properties are gotten in this cast composite.更多还原
