Deformation behavior of beta-titanium alloys

摘要: The cold workability of four solution-treated beta-titanium alloys was determined and related to the initial substructure. Two (TIMETAL-LCB Ti-15-3), which retained a well-developed subgrain structure after solution treatment, exhibited excellent workability, while those did not (VT22 TC6) inferior ductility. difference in explained terms variation strain-accommodation mechanism. Other factors that exacerbated observed low ductility latter two were also identified. These included occurrence deformation-induced martensite formation development multi-component textures, both may lead localization deformation at interphase or grain boundaries subsequent failure.
