【摘要】 研究了Ａｌ－ＴｉＢ＿２体系的燃烧合成过程。用粉末（Ａｌ、Ｔｉ、Ｂ）通过燃烧方法制备（Ａｌ－ＴｉＢ＿２）自生复合材料，采用ＤＴＡ、ＸＲＤ和ＳＥＭ技术对复合材料的形成和结果进行分析研究。得到如下结果：分别用８０％Ａｌ＋２０％（Ｔｉ＋２Ｂ）、９０％Ａｌ＋１０％（Ｔｉ＋２Ｂ）原料粉末，通过燃烧合成可得到Ａｌ－ＴｉＢ＿２，制备过程中产生少量ＴｉＡｌ＿３，Ａｌ基体与ＴｉＢ＿２结合紧密，无明显界面存在。更多还原

【Abstract】 This paper deals with the combustion synthesis of (A1,Ti,B) system, In-situ composite (A1-TiB2) was produced by combustion synthesis with powderls. The in-situ composite (A1-TiB2) wasanalysed and studied by DTA,XRD and SEM technique,The results were that A1-TiB2 was producedby combustion synthesis. The composition of raw materials were 80 % A1+ 20 % (Ti+2B) and 90 %A1 + 10% (Ti+ 2B). There was less TiA13 in the process, There are not clear boundaries between A1and TiB2.更多还原
