Abstract

The abrasive wear and cavitation erosion behavior of boron-ductilized Ni₃Al alloys has been studied and compared with that of several austenitic stainless steels. The abrasive wear resistance of the nickel aluminides was inferior to that of the stainless materials. This is attributed to the rapidly decreasing strength and ductility exhibited by Ni₃Al above 700 °C. However, the cavitation erosion resistance of the aluminides was found to be very good compared to the stainless steels. Surface orientation of individual grains was discovered to have a strong effect on erosion behavior of nickel aluminides. The Ll₂ crystallographic order is important in determining the resistance to both abrasion and erosion.
