The produced clad was studied for effects of heat treatment and carbonisation on the microstructural and hardness properties. The microstructural changes were summarized as: Laves/Eutectic-rich to primary dendritic to MC carbide rich to anisotropic Laves-rich to isotropic grain then finally precipitated and large MC carbides microstructure. The As-built sample had higher hardness value followed by the water quenched and carbonized samples which had similar hardness value. Aging and stress relieve conditions softened the sample. The obtained hardness values support the observed microstructures.AbstractenCarbonizationHardnessHeat treatmentsInconel 625Laser cladding and microstructuresArticle28132
