| 摘 要： | 采用机械球磨和热处理方法制备Ti3Al粉体,并将Ti3Al和C反应烧结制备Ti3AlC2陶瓷材料。将Ti、Al的摩尔比为3∶1的混合粉末,球磨20 h后经750℃热处理40 min得到质量分数达到98.54%的Ti3Al金属间化合物;然后采用Ti3Al和C的摩尔比为1∶2为原料,进行反应烧结制备Ti3AlC2,在1 300℃保温60 min,可得到试样中Ti3AlC2的质量分数为96.4%。研究得出Ti3AlC2的合成路径即在反应过程中先生成Ti2AlC和TiC两相,然后二者反应合成Ti3AlC2相。

| Abstract: | Ti3AlC2ceramic was synthesized by reaction sintering of C and Ti3 Al powders prepared by mechnical ball milling andheat treatment. The purity of Ti3 Al reaches 98.54% when the mixture powder with Ti and Al molar ratio of 3∶1 was ball milled for20 h, and heat treated at 750 ℃ for 40 min. Ti3AlC2 ceramic was synthesized by reaction sintering of Ti3 Al and C powders at molarratio of 1∶2 at 1 300 ℃ for 60 min. During reaction sintering, Ti2 AlC and TiC were formed first by the reaction of Ti3 Al and C, andthen the Ti3AlC2 ceramic was synthesized by the reaction of Ti2 AlC and TiC. |
