| 摘 要： | 研究了用ＸＤ（热爆）工艺合成ＴｉＡｌ合金及ＴｉＣ／ＴｉＡｌ复合材料,井探讨了其合成反应机制。结果表明,可在Ａｌ的熔点附近用ＸＤ工艺制备ＴｉＡｌ合金及其ＴｉＣ颗粒增强的ＴｉＣ／ＴｉＡｌ复合材料,Ｔｉ－Ａｌ粉末间的放热反应促进了ＴｉＣ的合成。ＴｉＡｌ合金由ＴｉＡｌ＋Ｔｉ３Ａｌ相组成,而ＴｉＣ／ＴｉＡｌ复合材料由ＴｉＣ＋ＴｉＡｌ＋Ｔｉ３Ａｌ相组成。

| Abstract: | D(exothermic dispersi on)synthesis and its reactive mechanism for the TiAl intermetallics and TiAl based composite reinforced with TiC particles are investigated.The exper-imental results show that TiAl intermetallics and TiC/TiAl composite can be achieved by the XD process at higher temperature than the melting point of aluminium and that the thermopositive reaction between Ti powder and Al powder,3Ti±Al→Ti3Al and Ti+Al→ TiAl,promotes the synthesis of TiC.TiAl intermetallics is composed of γ TiAl+α2 Ti3Al and TiC/TiAl composite is composed of TiAl+Ti3Al+TiC phases. |
