  1. The result of experiment showed that the reaction between ti and c is a thermodynamic course, when 2 wt % mg is added to melt, it can restrain the formation of fragility phase al3ti, and gained al matrix composite which contained tic reinforced particles only. because mg reacts with the forms a micro - high temperature field around the oxide around the graphite particles and the oxygen gas which is brought by the immersion bell, and the reaction gives out a lot of heat energy, thus forms many high micro - fields in melt, which prompt the reaction between the al and ti

    加入適量的mg ( 2wt )可以抑制tic al復合材料中的相al _ 3ti的產生,生成僅含tic的鋁基復合材料;由於活劑鎂在體系中與石墨顆粒周圍的、以及外來的反應放熱,在熔體中形成微高溫區,促進al - ti反應,同時, al - ti反應也是放熱反應,因此體系中的內能急劇增大,促使al _ 3ti分解以及ti朝c顆粒擴散,縮短反應的孕育時間。
  2. However the study of metal - oxide hetero - interface is relatively less because the properties of metals and oxides usually differ extremely from each other. contrary to metals, the oxides are usually very brittle, elastically stiffer, insulating and exhibit less thermal expansion and their crystal lattice constants are different from metals. moreover, the preparation of specimen of metal - oxide interface is very difficult, the observation of searching a suitable interface under the electron microscope is also a tedious work

    然而,對金屬-界面結構的研究卻相對少一些,這主要是由於金屬與之間的質相差非常大,與金屬相反,通常很、絕熱、熱膨脹系數小,晶格常數也不同於金屬,有的甚至相差很大,而且,制備金屬-界面比較困難,在電子顯微鏡下全面地觀察一個合適的界面也是一項令人乏味的工作。
