| 摘 要： | 在含２０．５ａ％Ａｌ的Ｎｉ３Ａｌ合金中加入铈的研究结果表明：（１）含饰量大约高于０．０４ｗｔ％合金的冷轧性能很差，无法轧成薄材；（２）含铈量为０．０１１ｗｔ％的Ｎｉ３Ａｌ合金，在５５０℃等温１２０ｈ和１２００℃等温０．５ｈ的室温延伸率可达１６％，σｂ为９００ＭＰａ左右，断口为穿晶断裂形貌，综合机械性能好；而７５０℃等温４０ｈ和１０００℃等温１ｈ的室温延伸率仅为３％，σｂ为５００ＭＰａ左右，断口为沿晶形貌，综合机械性能差。

| Abstract: | Our study on Ni3Al alloy containing 20.5at% of Al after addition of ceriumshows: 1)For the alloy with cerium of more than 0.04wt% added,it behaves bad in coldrolling and can't be rolled into light sheets;2)For the alloy with cerium of 0. 011wt?ded,when it is in the room temperature of 550C with isothermal 120h and 1200'C withisothermal 0. 5h respectively, its specific elongation can be up to 16%, is about 900MPa, the rapture assumes a transcrystalline profile and the combining mechanical behaviour is good,but when it is in the room temperatures of 750'C with isothermal 40h and1000'C with isothermal lh respectively,its specific elongation is only 3%,oh is about 500MPa,the rapture assumes a intergranular profile and the combining mech "ical behaviouris rather weak. |
