摘要
A hot-forged TiAl-based alloy having excellent oxidation resistance and high strength at high temperatures, and a process for producing such an alloy. A TiAl-based alloy comprising Al: (40+a) atomic % and Nb: b atomic %, with the remainder being Ti and unavoidable impurities, wherein a and b satisfy formulas (1) and (2) below.; 0≦a≦2 (1); 3+a≦b≦7+a (2);Also, a TiAl-based alloy comprising Al: (40+a) atomic % and Nb: b atomic %, and further comprising one or more elements selected from the group consisting of V: c atomic %, Cr: d atomic % and Mo: e atomic %, with the remainder being Ti and unavoidable impurities, wherein a to e satisfy formulas (3) to (9) shown below.; 0≦a≦2 (3); 3+a≦b+1.0c+1.8d+3.8e≦7+a (4); b≧2 (5); c≧0 (6); d≧0 (7); e≧0 (8); c+d+e0 (9)
