【Abstract】 Since icosahedral quasicrystalline phase (I-phase) has a new type of crystal structure has been found, it is reported that I-phase forms in a number of Ti-based alloys, and that the I-phase is well ordered and thermodynamically stable in the Ti-based alloy. Further, studies on the physical/ chemical, mechanical properties and other specific characteristic performances of the Ti-based I-phase alloys have received much attention. It is important from scientific and technological points to study the formation, phase transformation and mechanical properties of the alloys. Recently, we have examined the composition dependence of the structure as well as Ti-based nanoscale I-phase forming a-bility by melt-spinning and annealing techniques. An improvement in the forming abilities of nanoscale Ti-based I-phase alloy has been obtained. In this paper, the formation, structures and mechanical properties of the Ti-based nanoscale I-phase alloy have been reviewed.更多还原
