IMPROVED METHODS FOR THE PRODUCTION OF TITANIUM ALLOY EXTRUSIONS

Abstract

Several Ti-7Al-4Mo alloy billets were individually glass coated with no. 85, 383A and A-40 glass to determine billet contamination at 1800 F for heat soak periods of 45 and 90 minutes. Results of visual micro-examination and of a microhardness survey indicate: (1) glass-Ti reactivity is less for the 383A glass composition, and (2) the greater part of O contamination occurs during the first 45 min of heating. Installation of the 100-kw induction heating unit at the Allegheny Ludlum draw bench facility has been completed. Twelve Tee sections 4 ft long were selected on the basis of dimensional uniformity and minimum surface contamination. These sections were chemically pointed, pickled and annealed in preparation for the first warm drawing trials. (Author)
