SHS/PHIP技术制备TiC-30Fe金属陶瓷的显微组织及形成过程研究
Microstructure and Formation Mechanism of TiC 30Fe Cermet Fabricated by SHS
【摘要】 通过自蔓延高温合成结合准热等静压法（ＳＨＳ／ＰＨＩＰ）制备出了致密度为９６．３％的ＴｉＣ－３０ｗｔ％Ｆｅ金属陶瓷。分析了金属陶瓷的结构和组织，讨论了ＳＨＳ／ＰＨＩＰ制备金属陶瓷的材料结构形成过程。结果表明，金属陶瓷由近乎球形ＴｉＣ颗粒和Ｆｅ粘结相组成。粘结相Ｆｅ与ＴｉＣ之间有一较薄扩散层。
【Abstract】 In this paper, densified TiC 30wt%Fe cermet was produced by self propergating high temperature synthsis and pseudo hot isostatic pressing(SHS/PHIP) The composition and microstructure of the product were analysed A formation mechanism for the cermet made by SHS/PHIP was proposed The results show that the cermet consisted of quasi sphere TiC particles and Fe binder phase A thin diffused layer was found between Fe and TiC
