Iterative Taguchi Analysis: Optimizing the Grain Boundary Carbide in Hadfield Steel

Abstract:

Manganese steel (Hadfield) is one of the important alloys in industry due to its special properties. High work hardening ability with appropriate toughness and ductility are the properties that caused this alloy to be used in wear resistance parts and in high strength condition. Heat treatment is the main process through which the desired mechanical properties and microstructures are obtained in Hadfield steel. Iterations of Taguchi designed experiments and analysis were used to determine optimum heat treatment for minimizing grain boundary carbide content in Hadfield steel. Experimental variable chosen for this study included austenitizing temperature and time and rate of quenching. The austenitizing temperature and the cooling rate by changing in quenched solution were seen to have the greatest influence on carbide content in Hadfield steel.
