Hardness and Microstructure of Partially Austenitized 43XX Steel.
Abstract
A study was made of microstructures of several partially austenitized 43XX steels. By quenching from temperatures below those at which complete austenitization would occur, microstructures of martensite with ferrite and/or cementite were obtained. Microstructural analysis enabled the phase boundaries of the pertinent section of the phase diagram to be determined. Hardness changes in the as-quenched structures were correlated with the phase diagram. The major factor controlling the as-quenched hardness is the volume fraction and carbon content of the martensite in the structure. (Author)
