Patent ID: 7871247

Claim:
A high modulus turbine blade comprising: a base portion and a tip portion; a primary direction that extends from said base portion to said tip portion; and said turbine blade being formed of a base metal that has a crystallographic orientation, said crystallographic orientation having a high modulus direction, wherein said high modulus direction is aligned with said primary direction and is within either about ten degrees of the <112> crystallographic direction or about ten degrees of the <123> crystallographic direction, wherein said base metal is a nickel-based alloy composition comprising 1-16% Cr, a nonzero amount of 0-3% Mo, 3-13% W, a nonzero amount of 0-8% Re, a nonzero amount up to 14% Ta, 3-7% Al, a nonzero amount up to 20% Co, a nonzero amount up to 2% Hf, a nonzero amount up to 2% Ti, a nonzero amount up to 2% Nb, a nonzero amount up to 1% V, a nonzero amount up to 10% of at least one of Ru, Rh, Pd, Os, Ir, or Pt, a nonzero amount up to 0.25% Y, and the balance Ni.
