Paper Title:
Study of a New Chromium Carbide Reinforced Ni3Al Matrix Composite Hardfacing Material on IC6SX
  Abstract

The microstructure and property of a new high temperature surface wear-resistant chromium carbide/Ni3Al composite deposited onto IC6SX alloy by manual argon tungsten-arc welding.have been investigated The microstructures of the WL(welding layer), HAZ(heat affected zone), BM(base metal) were observed by SEM and Optical microscope and analyzed by EDS and EMPA. Since the large amount of Mo which diffused from the substrate IC6SX strongly effected the formation of hard phases in the welding layer, the microstructures of WL in this study turned out to be very different from former studies where the different materials were chosen as base metals. Due to the high welding temperature and the rapid cooling process, the microstructures in HAZ were much smaller than that in BM. And the microhardness tests results illustrated that the two materials were well metallurgically bonded.
