颗粒增强铝复合材料partieulate reinforeed alu-minium Composites以一定尺寸的颗粒弥散强化铝或铝合金基体制成的复合材料。 增强体作为增强体的颖粒,其主要作用为增强金属基体和本身承受载荷,从而明显地提高材料的刚度、力学性能、抗磨性能和降低热膨胀系数。所选用的陶瓷粒子颖粒,除具有高模量、高强度及良好的高温稳定性外,还必须考虑增强粒子与基体的相容性和化学稳定性。因为这是保证复合材料中二相之间界面状态良好从而有效地传递载荷的必要条件。一般情况下,根据基体合金的状态选择SIC、A12O3、TIC、TIBZ等陶瓷粒子作为增强体。他们的主要特征列于表1。颗粒可以为球形、多角形及片状等。 基体复合材料中的基体除在载荷条件下本身承载外,一个重要作用是将外界的载荷通过二相界面传输给增强颗粒。基体强度以及基体与颗粒间界面结合过弱,将无法使载荷有效传递。因此,在高温下复合材料的性能下降亦极为迅速,在软化的基体中增强效果将明显减少。增强铝肠粒的主要特征 密度(g/em3) E(GPa)UTS(GPa) a(X 10一6℃一l)Q自Q曰祖r上5,dl从J祖.1 .奋,-﹃b﹃b月任八jSICA12O3TICTIBZBoCSisN4BN3 .23 .944 .254 .52 .53 .22 .25 480 460 420 550 480 360100一5005 .46 .86 .53一60 .8 制备工艺颗粒增强铝复合材料是较成熟的一类金属基复合材料。制备工艺主要有粉末冶金法(见金属基复合材料粉末冶金法)和液相固化法(图1、图2)。由于SIC颖粒与铝基体之间的良好结合,有效地提高了铝及铝合金的弹性模量、抗拉强度、高温性能和耐磨性(表2)。70年代中期,SICP/AI复合材料也取得了令人瞩目的进展。目前世界上已建立一定规模的生产厂。
