ALUMINUM-NICKEL BASE ALLOY WHEREIN STRENGTH WAS IMPARTED TO INTERMETALLIC COMPOUND PHASE

摘要

57 A substantial increase in strength of a boron doped nickel aluminide is achieved by employing a substituent metal in the Ni3Al composition to replace a part of the aluminum. Vanadium and silicon are successfully substituted for a portion of the aluminum to provide a composition:where X is selected from the group consisting of vanadium or silicon.
