Öğe Effects of hot rolling on microstructures, wear and corrosion resistance of mo-ni-w p/m alloyed steels(Technical Faculty in Bor, 2024-11) Elkilani R.H.R.; Çuğ H.; Erden M.A.; Abushrenta H.; Albahlol O.; Cicek B.This study analyzes how hot rolling changes microstructure, tensile strength, wear, and corrosion behavior of Fe-0.55C3Mo-10Ni-0.5W alloy steel. The metal powders were pressed at 750 MPa pressure, and the cold-pressed samples were sintered for two hours at 5°C/min up to 1400°C in a mixed-gas environment of 90% nitrogen and 10% hydrogen. The steels produced were then hot rolled at 40% and 80% deformation rate. The microstructures demonstrate that MoC(N), WC(N), and MoWC(N) were produced and that the steels exhibited finer microstructures and better mechanical properties as the deformation rate increased. Wear decreased as the deformation rate increased. Furthermore, the the hot rolling method improved the corrosion resistance, as shown by the Tafel curve analysis. The greatest factor supporting the corrosion resistance was the increase in density value throughout the rolling process.
