Report on THE HOT EXTRUSION OF TITANIUM AND TITANIUM ALLOYS

摘要

This report summarizes the available information in published literature and Government research reports on the extrusion of titanium and titanium alloys, and also the information obtained in a survey of the companies currently extruding titanium. It includes a discussion of the requirements of the aircraft industry for titanium extrusions and the progress of the extrusion industry in meeting these requirements. The extrusion practices currently employed for the production of titanium alloy shapes and tubes, and the problems encountered in tooling, lubrication; billet heating, and heat treating are described. A final section gives a general dis¬cussion of the mechanical properties of extruded titanium and titanium alloys and the uniformity and reproducibility of these properties.
