| 摘 要： | 用冶金热力学理论计算出TiO2-H3BO3-Na3AlF6-Al-4.5Cu体系的起始反应温度,为950℃,并根据溶液热力学分析了TiB2颗粒形成的可能性.当熔体中Ti]、B]的摩尔比为1/2时,在熔体中形成TiB2颗粒;当熔体中Ti]、B]的摩尔比大于1/2时,熔体中除生成TiB2颗粒外,还形成TiAl3组织.

| Abstract: | The reaction mechanism of forming Al-4.5Cu/TiB2 composite was studied and the starting reaction temperature among TiO2, H3BO3, Na3AIF6, Al-4.5Cu solution was calculated to be 950 t by means of thermodynamics for reaction synthesis of TiB2 particles. TiB2 particles should be formed when the mole ratio of Ti] and B] was equal to 1/2 in the melt. But another product was TiAl3 structure besides TiB2 particles when the mole ratio of Ti] and B] was over 1/2. |
