| 摘 要： | 采用自蔓延高温合成法制备了ＮｉＡｌ金属间化合物，对合成的ＮｉＡｌ粉末进行高能球磨处理。Ｘ－ｒａｙ衍射分析表明：长时高能球磨处理后的ＮｉＡｌ粉末，其晶粒度显著减小，处理２００ｈ后，可获得晶粒尺度为３ｎｍ的ＮｉＡｌ纳米晶粉，这种纳米粉的显微硬度和比热与未处理的ＮｉＡｌ粉末相比有较大幅度的提高。

| Abstract: | High-energy ball milling process was used to treat the NiAl powder synthesized by SHS. X-ray deffrication analyses showed that grain size descreated obviously after long time treatement by ball milling. The NiAl nanocrystalline with 3nm could be achieved after-ball milling treatment of 200h,compared with raw NiAl powder,NiAl nano-powder's microhardness and capacity increased. |
