Abstract
β-Ti alloys with low Young’s modulus are always formed at the lower critical limit of β stabilization, where the β structure is prone to be destabilized. This present work aims at studying the structural stability of β-Ti alloy [(Mo0.5Sn0.5)-(Ti13Zr1)]Nb1 with low Young’s modulus (E) at different states of suction-cast (SC) and solution-treated (ST), and the deformation mechanisms of this alloy are also discussed. The solution treatment eliminates the composition heterogeneity of the SC alloy, and no second phases are precipitated from the β matrix, as a result of a further decrease of E from 48 GPa (SC) to 43 GPa (ST). After tension deformation, the stress-induced {112} $$ \langle 111\rangle $$ β twinning is dominant in the SC alloy, while the stress-induced phase transformation of β → α″ plays a decisive role in the ST alloy, which results from the different structural stabilities of β matrix at different states. The minor second-phase precipitation renders the matrix with a slightly higher β stability of the SC alloy than that of the ST one.
