Objetivo

Rail steel are designed to resist wear and rolling contact fatigue caused by forces transmitted through the wheel/rail contact zone. The aims of the project are twofold: to investigate morphology, transformation characteristics and properties of bainite mixed with a low amount of lath martensite, as compared to conventional pearlite structure, and to define chemical compositions, for given hot rolling and in line/off line cooling conditions to achieve the optimum bainitic structure able to develop hardness values higher than 400 HB minimum tensile strength of 1400 MPa, good wear resistance and elongation = 10%. The welding behaviour will also be studied.
