【摘要】 采用ＳＨＳ／ＰＨＩＰ 工艺制备了致密的ＴｉＣＡｌ２Ｏ３Ｆｅ 复合材料。研究了Ｆｅ 含量对燃烧温度、燃烧波速度、合成产物密实度及力学性能的影响。结果表明， 燃烧波速度在一定Ｆｅ 含量范围内出现一近似平台； 密实度随Ｆｅ 含量变化而变化， 在Ｆｅ 含量为１０ ％ 时， 产物的密实度最高， 为９９ ．４ ％ ； 随着Ｆｅ 含量的增加产物的抗弯强度不断提高， Ｆｅ 含量为１０ ％ 和３０ ％ 时， 抗弯强度分别为７４０ ＭＰａ 和９７０ＭＰａ 。更多还原

【Abstract】 The influence of Fe content on combustion temperature, combustion velosity, density and mechanical properties of TiC Al 2O 3 x Fe composites fabricated by SHS/PHIP was studied. The results show that the combustion velosity has an approximate plateau, when the content of Fe is between 20%～30%; the densities of products vary with content of Fe and reach up to the highest(i.e. 99.4%), when the content of Fe is 10%; the transverse rupture is increased with Fe content, e.g. when Fe contents are 10% and 30% the transverse rupture are 740 MPa and 970 MPa, respectively.更多还原
