ABSTRACT:
A method is taught for rendering a boron-doped tri-nickel aluminide resistant to mechanical failure while at intermediate temperatures of 600.degree. C. to 800.degree. C. due to a hot-short phenomena. The method involves incorporating between 0.05 and 0.30 of cobalt in the composition according to the expression
