ABSTRACT:
A method for thermomechanically processing gamma titanium aluminide alloy wrought products comprises the following steps: a) a near gamma titanium aluminide alloy ingot is cast; b) the ingot is hot isostatically pressed (HIP'ed) to seal off casting defects; c) the HIP'ed ingot is prepared into suitable forging preforms with or without intermediate homogenization heat treatment; d) the forging preforms are isothermally forged into suitable end product preforms at temperatures sufficiently close to the phase line between the alpha+gamma and alpha-two+gamma phase fields so as to break down the ingot microstructure and to yield a largely equiaxed gamma microstructure; and e) the end product preforms are processed into the desired wrought end products through a controlled rolling process or a closed-die forging operation.
