Abstract

This paper presents the results of a study of microstructure and mechanical properties (tensile and creep behavior) of a multicomponent body-centered-cubic Nb-35Ti-6Al-5Cr-8V-1W-0.5Mo-0.3Hf-0.5C alloy (compositions quoted in atomic% unless stated otherwise). The double extruded material is shown to have a Van Gogh Sky microstructure that is formed a? a result of the combined effects of microsegregation and deformation gradients. The effects of recrystallization heat treatments on microstructure were examined in an effort to produce a fully recrystallized microstructure. The changes in tensile properties and fracture mechanisms at different temperatures (27-704 °C) are discussed for material in fully recrystallized condition. The micromechanisms of creep deformation at 704 °C are also elucidated for the fully recrystallized condition.
