Description
Summary:Precipitation hardening is a widely used method for hardening materials. The degree of dispersity of the segregations is a fundamental parameter determining the strength of alloys. Bernshtein et al. [2] note that the high-temperature heat treatment of steel provides finer carbides after high-temperature tempering than conventional quenching. Such a treatment accompanied by the creation of enhanced dislocation density provides a more uniform distribution of carbides. It is also shown in [2] that after tempering at 400 deg C segregated equiaxial disperse carbides about 30 nm in size predominantly occur over twins and boundaries of the former crystals.
