The Cyclic Stress-Strain Response of Titanium-Vanadium Alloys.

Abstract

The cyclic stress-strain response of four Ti-V alloys (24, 28, 32 and 36 wt % V) which have deformation modes ranging from coarse twinning to wavy and planar slip, has been measured and correlated with deformation mode and microstructure. When coarse twinning is the primary deformation mode an anamolous Bauschinger effect, associated with untwinning during load reversal, is observed. A saturation flow stress is not obtained for the wavy slip alloy due to the intervention of microtwinning which inhibits cross slip and cell formation. Cyclic hardening of all alloys appears to be related, in some degree, to deformation twinning. Cyclic softening occurs for the planar slip alloys in the absence of microtwinning due to increasing mobile dislocation density. (Author)
