The effect of deformation and quenching temperature on the mechanism of decomposition in steel EI702

  • Published:
Soviet Physics Journal Aims and scope

Abstract

It is shown that the mechanism of decomposition in steel EI702 is determined by the quenching temperature and the degree of prior deformation. On aging after quenching from low temperatures or after heavy deformation, the principal mechanism of decomposition, in which the γ'-phase is formed, is discontinuous precipitation. However, on aging after quenching from high temperatures, the principal mechanism is continuous decomposition. It is found that discontinuous decomposition in steel E1702 is a very desirable process, since by accelerating aging it greatly increases the strength characteristics. The nature of the effect of the quenching temperature on the mechanism of decomposition in steel E1702 is discussed.
