摘要：
In this paper, the Ni and Ti powder mixture with equiatomic ratio was high energy ball milled and then consolidated by explosive compaction. The microstructures of as-compacted and heat treated bulk samples after explosive consolidation are investigated in detail by transmission electron microscopy (TEM) and high resolution electron microscopy (HREM). The experiment results reveal the microstructure variation during mechanical alloying in Ni-Ti binary systems. It is found that a metastable phase denoted as I phase formed during ball milling and the structure of I phase was determined by both electron diffraction and HREM. Finally, the mechanism of amorphization induced by ball milling was discussed.
