Abstract

The microstructures of two nickel based alloys Ni-Cr-Al-C-(Nb) containing chromium and chromium plus niobium carbides were investigated. These alloys unlike commercially available nickel based superalloys contain a high volume fraction of carbides to obtain high wear resistance. Moreover aluminum addition enables precipitation hardening of the nickel based matrix. Scanning electron microscopy (SEM) including energy-dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD) studies were carried out with particular attention to phase composition of materials.

Keywords: nickel based alloys, carbides, cast alloy, SEM
