Abstract Scope For Ti and Zr, ω-phase is the high-pressure phase and bcc is the high-temperature phase. In this work, we perform molecular dynamics simulations to study the deformation process of ω-Ti at low temperature and bcc-Ti at high temperature. We observe extensive ω-hcp and bcc-hcp phase transformation and the formation of rich martensite microstructure. Moreover, for the first time, we demonstrate that four types of transformation twins can be formed through the ω-α phase transformation or bcc-hcp phase transformation. The calculations of deformation gradients and transformation strains reveal that different types of transformation twins are favored by the specific loading directions.
