The effect of misch metal and yttrium on the ageing behavior of AZ91 magnesium alloy was investigated.Aluminum compounds of rare earth and yttrium with high melting point were crystallized fiirstly from the melt alloy during the solidifying process and pushed to the crystalllizing face of α phase to inhibit its growing,or became the nucleation of the matrix.

在AZ91镁合金中添加稀土和钇之后，高熔点的铝稀土化合物和铝钇化合物在凝固过程中首先结晶析出，并成为基体相的形核中心，或者被推移到初生α相结晶前沿，阻碍α相的生长，使其铸态组织得到细化。

The results show that constitutional phases in the 〓 alloy is the same as that in the 〓 alloy, but phase composition and transformation temperatures of two alloys are quite different. The Ms temperature of the 〓 alloy is lower than-180℃. In order to enable the alloy to be used for making pipe couplings, it is necessary to control Al addition and to increase Ti addition in the alloy. In the 〓 alloy, there exist three constitutional phases: TiNi matrix phase with B19′structure,β-Ta phase and NiTa〓 phase. Transformation temperatures, M〓, Ms, As and A〓, of the alloy are 55℃, 66℃, 94℃ and 109℃, respectively.

结果表明，〓合金显微组织的相组成物与〓合金一样，但相成分明显不同，相变温度相差较大，其Ms温度低于-180℃，要想使该系合金用于制作记忆合金管接头，必须控制铝的添加量并提高合金中的钛含量使合金的Ms温度控制在-80℃～-100℃之间；〓合金是由具有B19'结构的TiNi基体相、β—Ta固溶体和NiTa〓化合物三相组成的，其相变温度M〓、Ms、As和A〓分别为：55℃、66℃、94℃和109℃。

Because there are many kinds of matrixes in titanium matrix composite, we select some typical ones as investigated subject in many titanium alloys or titanium aluminide intermetallics, and then simulate the distribution of thermal residual stresses under the appropriate composites fabrication and heat treatment parameter. We not only hope to seek better titanium matrix, but also discover the relationship between the material properties and the thermal residual stresses, and then provide some theoretical guidance for the selection of the matrix in titanium matrix composites.
