The present symposium on microstructure/property relationships in titanium aluminides and alloys discusses gamma titanium aluminides (ingot metallurgy alloys), gamma titanium aluminides (cast, PM, and XD alloys), alpha-2 titanium aluminides, and structural titanium alloys. Attention is given to phase equilibria in Ti-Al alloys, high-temperature phase stability in the Ti-Al-Ta system, dislocation structure in deformed gamma/alpha-2 titanium aluminides, and the microstructure-property correlation in TiAl-base alloys. Topics addressed include the temperature dependence of the tensile behavior of a gamma titanium aluminide alloy, the plastic flow behavior of a Ti-Al-Nb-Mn alloy at high temperatures, and hydrogen embrittlement in gamma TiAl alloys. Also discussed are microstructure morphology effects on the fracture toughness of a cast near-gamma titanium aluminide alloy, the creep behavior of Ti-24Al-11Nb, the flow behavior of Ti-24Al-11Nb at high strain rates, and the role of hydrogen-assisted cracking in SCC of alpha-beta Ti alloys.
