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９７．７％的ＴｉＣ－Ａｌ２Ｏ３－２０Ｆｅ金属陶瓷（ＴＡＦ２０）。分析了金属陶瓷的相组成、微观组织及性能。结果表明：金属陶瓷由ＴｉＣ，Ａｌ２Ｏ３陶瓷颗粒和Ｆｅ粘结相组成；粘结相中Ｆｅ与Ａｌ２Ｏ３之间的界面光滑，与ＴｉＣ之间有一薄的扩散层；ＴＡＦ２０金属陶瓷的抗弯强度和抗压强度分别为８９０ＭＰａ和１８．４ＧＰａ。
Densified TiCAl2O320Fe cermet was produced by selfpropagating high temperature synthesis and pseudohot isostatic pressing(SHS/PHIP) The composition, microstructure and properties of the product were analyzed The results show that the cermet consists of TiC and Al2O3 particles and quasicontinuous Febinder phase The interfacial bonding between Fe and Al2O3 is smooth Transverse rupture strength and compressive strength are approximately 890MPa and 184GPa
