Abstract:

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 12 power. 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
