Abstract

Dynamic phase transformation during subtransus forging was investigated in a powder metallurgy (PM) Ti1.5Fe2.25Mo alloy. The results show that compressive deformation restrains the hcp (α)→bcc (β) phase transformation, and induces a local martensitic transformation in the deformed sample during subsequent cooling. Thermodynamic analysis confirms the feasibility of these transformations.
