TANTALUM EXTRUSION PROGRAM. STATE-OF-THE-ART SURVEY

Abstract

A state-of-the-art survey of the extrusion technology and Ta alloys was completed. A survey of physical and mechanical property data and present day fabrication know-how for ingot production and extrusion practice is presented. There are a limited number (11) of Ta alloys for which data exists. The alloy chosen for this program is the Ta-10% W alloy. Very little data is available on extruding Ta alloys. The state-of-the-art survey will be a guide in determining the necessary melting practice and initial breakdown of the Ta-10% W ingots. It was recommended that electron-beam melting be used in initial melting of the alloy and that consumable-electrode arcmelting be considered for finish melting of the alloy ingots for extrusion, and that simple extrusions be employed in the Phase II evaluation to assess the merits of preworked, recrystallized billets for the extrusion of a Tee section.
