Dilatometric Study of Phase Transformations in Steels: Some Issues

CODEN: MPCACD

Abstract

Dilatometry is widely used in the investigation of phase transformation in steels, not only by research laboratories but also by most steel makers. Its application includes the determination of CCT and TTT diagrams, and more generally the investigation of phase transformation kinetics under controlled temperature conditions. A basic and often undiscussed assumption in the exploitation of dilatation measurements as a function of temperature is that of a constant and uniform temperature distribution in the specimen, and of a homogeneous material. In the present paper, various issues encountered with a widely used quenching dilatometer were discussed, including longitudinal temperature gradients, deformation anisotropy, or vacuum evaporation of some chemical species.
