2. Modelling and Characterisation of the Martensite Formation in Low Alloyed Carbon Steels
Abstract : The current work contains experimental and theoretical work about the formation of martensite from the austenitic state of the steel Hardox 450. Simulation of rolling and subsequent quenching of martensitic steel plates requires a model that can account for previous deformation, current stresses and the temperature history, therefore dilatometry experiments were performed, with and without deformation.

3. Low Temperature Austenite Decomposition in Carbon Steels
Abstract : Martensitic steels have become very important engineering materials in modern society. Crucial parts of everyday products are made of martensitic steels, from surgical needles and razor blades to car components and large-scale excavators. READ MORE

4. Development of Structural Steels for Powder Bed Fusion - Laser Beam
Abstract : Over the past decade, powder bed fusion – laser beam (PBF-LB) has attracted noticeable attention from both academia and industry. However, there remains a scarcity of approved material for the process, as fewer than 40 alloys are commercially available. READ MORE

5. Railway Wheel Flats. Martensite Formation, Residual Stresses, and Crack Propagation
Abstract : A railway wheel flat is a flat spot on the rolling surface of a wheel caused by its unintentional sliding on the rail. The reason for the sliding may be poorly adjusted, frozen or defect brakes, or too high braking forces in relation to the available wheel/rail adhesion. READ MORE
