Abstract

The beta titanium alloys offer many advantages in terms of processing, mechanical properties, and low cost of fabricated components compared to conventional titanium alloys. However, in the past, melting difficulties, reproducibility problems, and the conservatism of designers resulted in only one major application—on the SR-71 “Blackbird,” Mach 3+ surveillance airplane. This paper discusses the characteristics of the beta titanium alloys— from melting, through processing, to final microstructure and mechanical properties— and suggests that with recent advances the time is now ripe for the titanium community to successfully fend off competition from other materials by making increased use of this alloy class.*
