Abstract
Transmission Electron Microscopy (TEM) studies have been done on Ti--V alloys before and after application of high pressure to check the stacking soliton model of the diffuse omega phase. gb-ω transformation under high pressure was noticed in Ti0.81 V0.19 and Ti0.72 V0.28 alloys, thereby proving that ω -clusters prefer a smaller lattice parameter than that of the β-phase. However, the β-ω cell constant discrepancy is too small compared to theoretical predictions. Further, pressure causes incommensurate to commensurate phase transition. These results point out to the inadequacies of one-dimensional theories for diffuse omega phase.
