  • Mo-Hf-C alloy composition
    Patent number: 4657735
    Abstract: A molybdenum-hafnium-carbon alloy is provided consisting essentially by weight of about 0.6% to about 1% Hf, about 0.045% to about 0.08% C, and the balance essentially molybdenum, the alloy being characterized such that during casting of an ingot and hot forging of a billet thereof, it has a substantially less tendency to crack compared to alloys containing Hf in excess of about 1% by weight and carbon in excess of 0.08% by weight, without substantial diminution in strength properties of said alloy at elevated temperatures.
