Abstract

The decrease in dislocation density and hence the high strength loss can be modelled during martensite tempering as a recovery process. In this work, an innovative approach is presented to understand the role of silicon associated with the inhibition of the recovery rate. A phenomenological model is presented, where a combination of cross-slip and solute drag is identified as the main governing mechanism for recovery up to 450 (Formula presented.) C, from where it is postulated that recrystallisation occurs.
