Hydrostatic extrusion process of rods through conical die by element - free method 棒材通過錐形模靜液擠壓成形的無網(wǎng)格法分析
And then hot hydrostatic extrusion is used to press the sintered billets . the following aspects have been researched on 對粉體坯料進(jìn)行低溫真空反應(yīng)燒結(jié)和高溫真空反應(yīng)燒結(jié),以得到致密度較高的燒結(jié)坯。
Therefore , a new technology , which consists of the mechanical milling ( mm ) , reactive sintering and hot hydrostatic extrusion has been put forward 本文采用機械球磨?反應(yīng)燒結(jié)?熱靜液擠壓方法,有望成為制備高性能ti - al基合金的有效途徑。
By x - ray analysis of the obtained samples the degree of the reaction was researched when the time of ball milling changed . at last the regularity of the metallurgical structure of tial alloy was investigated , when the high temperature changed . the following aspects were accomplished after hot hydrostatic extrusion 熱靜液擠壓工藝:擠壓后,坯料致密度有了較大的提高;分析了球磨時間跟擠壓力的關(guān)系;對ti - al基合金室溫斷裂方式及斷口形貌進(jìn)行了一定的研究。
