Abstract

Forming of titanium alloys, especially at room temperature, presents considerable difficulties due to a tendency to adhere to the tooling. The high frictional forces combined with the high yield strength and limited ductility of these materials at room temperature practically necessitates forming at elevated temperatures. There thus exists a need for developing new lubricant systems for the forming of titanium alloys at temperatures above 300F. It is well established that friction contributes not only to the forming loads but also to work-piece surface quality and to tooling deterioration. In view of these effects the authors have been most active on the development of lubricants suitable for warm forming operations over the last three years.
