Abstract

Titanium foam was produced by expansion of pressurized argon-filled pores within titanium at 860 °C. Alternating atmospheres of pure Ar and Ar/4% H2 resulted in cyclical hydrogen alloying/de-alloying. The associated internal-stress plasticity enhanced pore expansion, volume fraction and size, as compared to foams expanding by creep without composition change.
