The electrical discharge machining (EDM) behaviour of sintered Ni3Al was carried out with different process variables. The metal removal rates were found to increase with the applied current and pulse on-time. The surface roughness of Ni3Al increased with pulse-on time. Cracks were formed on Ni3Al surface during the EDM operation due to generation of high thermal stress. No phase changes were found on the machined surface due to the EDM operation. The debris analysis showed solidification of liquid materials into non-crystalline spheres.
