Stresses and phase transformations occurring in quenching of carburized steel gear wheel

Abstract

AbstractA method for analysing temperature, metallic structures, stress and strain, and carbon content during the carburized quenching of a steel gear is presented, and the results of calculations using the finite element method are compared with experimentally measured data. Since carburization precedes quenching, a diffusion equation is solved in order to determine the carbon content. Calculated profiles of temperature, stresses, and martensite and pearlite volume fractions during quenching are presented, and the effects of coupling between them are also considered.MST/19
