Abstract
Density measurements and data on the mechanical properties of titanium–tin alloys, fabricated by powder metallurgy from sodium-reduced titanium, are reported.
Low porosities were achieved after a single pressing and sintering operation. A typical set of preparation conditions involved compacting at 40 tons/in.2 and sintering, in vacuum, at 1300° C. for 1 hr. With tin contents above 5%, evaporation of tin during sintering could prove troublesome.
The presence of tin strengthened titanium markedly. The addition of 15% tin increased the ultimate tensile stress at room temperature by ∼90%, with a corresponding, though less marked, reduction in ductility.
