研究了纳米晶Ni-Cr-Al合金的高温氧化行为，发现与 铸态合金不同，随成分不同纳米晶合金在1000℃氧化时，氧化物可分为四个区：A单一Al2O3区；B复杂氧化膜含一连续Al2O3内层区； C复杂氧化膜含内氧化物区；D Al2O3和NiAl2O4共生区.纳米晶化明显扩展了Al2O3生成区的成份范围.
High temperature oxidation behavior of nanocrystalline Ni-Cr-Al superalloys was studied.It was found that with difference from cast alloys,the obtained oxide map for high temperature oxidation of the nanocrysta lline alloys may be divided into four areas. Nanocrystallization can remarkably expand the area of formation of Al2O3 scales in the map.
