Design of new economic secondary precipitating steels for fatigue resistance at elevated service temperatures

ended

The aim of this project is to investigate the microstructure evolution due to tempering of nanobainitic steels and their properties. Furthermore this project will be the first attempt to evaluate the potential of a new class of steel combining nanostructured bainitic steels with secondary precipitation. Potential applications are subjected to elevated temperatures and require high fatigue performances at these temperatures (e.g. gas injection components, bearings, gears). Indeed, it is hoped that this yet untested combination will lead to an economical yet very high performance material for use at elevated temperatures.
