Abstract

Inspired from the superior mechanical properties of TRIP/TWIP steels (TRIP for transformation induced plasticity and TWIP for twinning induced plasticity), a new type of metastable β Ti-alloys showing combined TRIP/TWIP effects through controlling the β stability of Ti-alloys was reviewed. The alloys were designed based on the "d-electron alloy design method" and controlling of electron/atom ratio (e/a). The results show that so-designed alloys display excellent combination of high strength (ultimate tensile strength 900~1200 MPa), high ductility (uniform elongation 40%) and improved work-hardening behavior. The detailed microstructural analysis indicates that the superior performances arise from the synergic effects between α˝ phase transformation induced plasticity (TRIP) and {332}<113> twinning induced plasticity (TWIP).
