Abstract

Abstract : Thermal ageing of 100Cr6 with different initial austenitisings was studied using the combination of synchrotron X-ray diffraction and dimensional variation measurements. Synchrotron X-ray diffraction provided the phase volume fractions and their carbon content through the analysis of the lattice parameters. Dimensional measurements were obtained in situ in a quench dilatometer also used to realise the heat treatment. The combined analysis of these data provides a better understanding of phase evolutions. For the different austenitising treatments investigated, the dimensional variations were found to be easily linked to the phase parameters measured by X-ray diffraction.
