ABSTRACT:
A novel titanium base alloy having a micrograph with alpha plates oriented in three directions with respect to their parent beta grains, but with alpha plates so short that no basketweave pattern is evident. The alloy contains from 0.02 to 2.0 atomic percent boron; 6 to 30 atomic percent aluminum; 0 to 4 atomic percent tin; 0 to 4 atomic percent gallium; and may contain 0 to 6 atomic percent zirconium of hafnium or a mixture of the two; 0 to 12 atomic percent of at least one metal selected from the group consisting of vanadium, columbium, tantalum, chromium, molybdenum, rhenium, tungsten, ruthenium, and the platinum group metals; and from 0 to 2 atomic percent of at least one element selected from the group consisting of yttrium, carbon and the rare earth metals.
