Abstract

The purpose of this study is to investigate the textural changing process and the structural changing process of commensurate ω phase during tensile deformation in the metastable β-type Ti-14 mass%Mo alloy that is formed commensurate ω phase by quench. Optical microscopy, X-ray diffraction and transmission electron microscopy were performed for the specimens that were deformed until different tensile strain. In the 5%-strained specimen, many {332} 〈113〉 twins were formed, and commensurate ω phase of specific variant induced upon tensile deformation. In the 25%-strained specimen, secondary twins or slips which divided early formed {332} 〈113〉 twins into pieces were observed. Fine divided deformation texture was observed in the specimen after fracture, and it is considered that commensurate ω phase changed into incommensurate ω phase or transformed reversely to the β phase. The changing processes of deformation texture and commensurate ω phase were indicated from these results.
