Deformation and Solid Solution Strengthening of BCC Titanium-Vanadium Alloys.

摘要

The influence of oxygen on the strength and deformation behavior of Ti-40V single crystals containing various amounts of oxygen has been examined. The flow stress has been analytically separated into a thermally activated component (tau*) and an athermal component (tau sub mu). It is shown that tau*increases linearly with oxygen concentration (C),whereas tau sub mu increases as C to the 1/2power. Oxygen also tends to reduce the tendency for planar slip by enhancing cross slip. The implications of these effects on the properties of bcc Ti alloys are discussed. (Author)
