Elliott-Bowman, B.; Cook, A. C.; Brown, P.; Dye, D. and Qin, R. S. (2015). Altering the microstructure of pearlitic steel using pulsed electric current. In: Sustainable Materials Science and Technology, 15-17 Jul 2015, Paris.

Abstract

Pearlitic steel is widely used in many industries due to its inherent strength and toughness. It can have a tensile strength in excess of 6GPa in the cold- drawn state [1] and its properties and machinability can be altered through heat treatments, such as spheroidisation annealing [2]. While spheroidisation treatments are widely used, they reduce the hardness of pearlitic steel and are often lengthy, taking over ten hours to complete
