摘要

The changes in mechanical properties and formability of β-type Ti-Mo alloys with Mo content were investigated. Three types of Ti-Mo alloys, Ti-8massMo, Ti-14massMo and Ti-20massMo were prepared, and a monotonic tensile test, a cyclic tensile test and a conical cup drawing test were conducted. It was found that Ti-Mo alloys are superior to Ti6A14V in cold formability though inferior in tensile strength. Ti-14Mo was found to have excellent deep drawability as well as tensile ductility due to the twin formation. Ti-20Mo, of which the primary deformation mechanism is coarse slip, exhibited inferior tensile ductility but relatively high deep drawability. Ti-8Mo showed intermediate properties concerning cold formability, while it exhibited pseudo elastic type loading-unloading behavior, because of stress induced martensite transformation.
