Chemically Patterned Steels

A new type of microstructure design concept for high strength steels, consisting of a nanolaminate of martensite and austenite, was recently demonstrated using an approach termed ‘chemical patterning’. The chemically-patterned steels can generate an excellent combination of ultimate tensile strength and total elongation. This thesis involves both experiments and simulations to develop an in-depth understanding of the chemically-patterned steels from many aspects including the heat treatment, the tensile response, the wear behaviour, the new alloy design etc.
