The main conclusions are as follows : ( 1 ) o ' - sialon / sic has been prepared by reactive sintering techniques 得出如下结论: ( 1 )以si粉、粘土和sic粉为原料,采用反应烧结工艺低成本制备了力学性能优良的o ' - sialon sic陶瓷材料。
Therefore , a new technology , which consists of the mechanical milling ( mm ) , reactive sintering and hot hydrostatic extrusion has been put forward 本文采用机械球磨?反应烧结?热静液挤压方法,有望成为制备高性能ti - al基合金的有效途径。
The material of the experiment is compact ti / al composite powders prepared by high energy ball milling . the compact ti / al composite needs reactive sintering at low temperature and high temperature , in order to get high densified tial alloy 本文实验方法是,球磨不同时间的ti / al复合粉,然后在一定压力下冷压或者300 400下热压制坯。
The expansion and dehiscence behavior during the vacuum reactive sintering below 660 of compact ti / al composite powders was experimentally investigated , and the reasons of expansion and dehiscence were theoretically analyzed . the method of low temperature reactive sintering was generalized , and the experiment testified the method effective . the rule of the expansion of the billets was generalized from the result of density of the billets 低温反应烧结工艺:研究了高能球磨ti / al复合粉体在温度低于660下真空无压反应烧结过程中的膨胀和开裂行为,分析了产生膨胀和开裂的主要原因;并提出了能够有效预防坯料开裂的方法;通过测定坯料在低温烧结后的密度,总结了其体积膨胀的规律;通过x射线衍射技术分析了随球磨时间不同,金属间化合物的生成情况。
