ABSTRACT:
It had been found previously that tri-nickel aluminide compositions are quite sensitive to the ratio of nickel to aluminum in their ability to receive boron as a dopant. It has now been found that compositions which are relatively poor in the aluminum component can be doped more effectively with a combination of boron and zirconium. It has been found for the nickel aluminides which have lower concentrations of aluminum that the percent of zirconium and boron which can be added to the composition to effectively increase the strength of the alloys is favored by the lower aluminum ratio. The compositions which result are found to have significant strength properties not only at room temperature but at elevated temperatures based on tensile tests of the compositions.
