Accurate analysis of phase changes
The aim of this project is to strengthen the research infrastructure of the Steel Research Centre, as well as to accelerate the development and manufacture of new high-strength steels, as well as cost-effective steel grades with higher corrosion resistance. This can be achieved through the introduction of the state-of-the-art dilatometer equipment for rapid sample heating/cooling speeds. This allows for the observation of phase transformations of the test material from 1 500 °C to room temperature. This possibility is currently not available for material researchers in Finland and the equipment serves the needs of both CASR and industry.In the development of materials and especially steels, it is not enough to increase strength alone. For example, toughness, formability, hardness and fatigue duration are characteristics that are difficult to achieve together with high strength. This requires an accurate analysis of the development of microstructure and of the variables that achieve the optimal microstructure and the desired mechanical properties. This dilatometer equipment is an essential factor in the study of microstructure changes. The project includes in practice the investment and commissioning of the equipment. As a result of the project, the University has the capacity and resources to quickly and efficiently determine phase changes in various materials in its own basic research and industrial product development projects. Practical research will be integrated into existing research projects, but the equipment will also open the door to new types of research projects. The dilatometer equipment that allows rapid heating and cooling is unique in Finland, which is why the project will also increase the attractiveness of the University of Oulu and CASR. The aim is therefore also to increase funding through public projects and service research.
