| 摘 要： | 为了有效控制Al-Ti-B合金线材微观组织中的TiAl3化合物颗粒的状态,研究了Al-Ti-B合金熔体进行电磁搅拌与连续铸挤线材成形过程中,搅拌温度及搅拌时间对化合物TiAl3颗粒的大小、形态及分布的影响。结果表明,电磁搅拌时间的延长可以使TiAl3颗粒的聚集现象消除,颗粒破碎细化,分布趋于均匀,电磁搅拌30min可达到最佳效果;搅拌温度直接影响熔体粘滞力的大小,搅拌温度升高可消除TiAl3颗粒团聚带,改善颗粒的分布,电磁搅拌温度控制在800℃为最佳。

| Abstract: | To effectively control the morphology of TiAl3 compound particle in microstructure of Al-Ti-B wire, effects of different electromagnetic stirring time and temperature on the size, shape and distribution of TiAl3 phase during electromagnetic stirring and CASTEX deformation of Al-Ti-B melt were investigated by OM (optical microscope), SEM (scanning electron microscope) and XRD (X-ray diffraction). The results show that with increasing in electromagnetic stirring time, the conglomeration of TiAl3 phase disappe... |
