METHOD FOR IMPARTING STRENGTH TO INTERMETALLIC PHASES

摘要

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: (Ni0.75Al0.20X0.05)99B1 where X is selected from the group consisting of vanadium or silicon.
