N一3AIJ一J旧shuJ一an huahewu goowen heJ一nNi3AI基金属间化合物高温合金(Ni3AI一baseintermetallie eompound superalloy)以Ni3AI相为基体的金属间化合物高温合金。Ni3AI作为高温合金材料中的强化相口)早已被人们所熟知。单晶Ni3AI有较好的室温塑性和加工性,但多晶Ni3AI在室温的塑性儿乎为零。1979年,日本和泉修等发现,添加微量硼可使Ni3AI韧化。硼强烈地偏聚于晶界,从而提高晶界的结合强度并使晶界区无序化,因此提高了晶界区塑性变形能力,使Ni3AI的室温拉伸伸长率可达50%以上。纯净N珠AI的室温、高温强度偏低,与高温合金相比需要进一步提高。固溶强化(见高温合金固溶强化)是提高强度的一条有效途径。Ni3AI可以固溶很多元素,其中以错和铅的强化效果最显著。美国橡树岭国家试验室已发展了一系列含铬、错、错等元素的Ni3AI基金属间化合物高温合金,具有良好的强度、塑性和高温抗氧化性。中国也对Ni3AI基合金进行了深入研究,并添加微量镁显著改善了热加工塑性。Ni3AI基合金可能是最先在工业上得到使用的金属间化合物高温合金之一,已制成各种部件在试用,如汽轮机和柴油机的耐热部件、高温模具、加热元件以及航空用的紧固件等。 〔邹敦叙)
