An EBSD Study of Austenite Formation and Stability in Low-Alloy TRIP Steels

Article Preview

Abstract:

Work has been carried out at KIMAB to determine the best, industrially feasible, conditions for producing TRIP steel sheet with the aim of obtaining a tensile strength of 600 MPa and a ductility of 30% through a hot-dip galvanising process schedule. Two of the most promising steels were selected to study the microstructures and to follow the transformation from ferrite to austenite in more detail, as well as to examine the stability of the austenite during deformation. This investigation has been performed mainly with the aid of the EBSD technique.
