Effect of Heat Treatment on Microstructure and Corrosion Resistance of Ni-Cr-Mo-Fe Alloys
The effects of heat treatment on microstructure and corrosion resistance of Ni-Cr-Mo-Fe nickel-based alloys were investigated by X-ray diffraction (XRD),metallographic microscope (MM),scanning electron microscopy (SEM) and electrochemical analysis,respectively.Experimental results indicated that the samples which were prepared via electric arc melting shielded by argon were pure solid solutions with homogeneous microstructure.Segregation of chromium element and slightly smaller grain size were found after heat treatment.Better corrosion resistance of samples was achieved after heat treatment,due to improvement of microstructure,morphology and distribution of elements.
