HighT – Development of High Technology Castings

Enhanced production and post production techniques and materials optimisation, performed in the project “HighT – Development of High-Technology Castings, have enabled production of cast components with improved mechanical and wear properties as well as lower weight and less variation in properties. Within the project three important fields have been studied; High-Strength Cast Iron, Lightweight Components and Combining materials though casting. The results from the work with High-Strength Cast Iron have enabled production of solution hardened castings with both thin and tick wall sections. By enhanced production of molds and cores, the spread in component properties has also been reduced. Within the work regarding Lightweigt Components, the microstucure and pore content levels have been related to mechanical strength. Also, methods for modelling of residual stresses have been proposed. By combining casting simulation and casting trials, the work related to New Technologies has resulted in an technoque for combining different materials thorugh casting. With this technique, it is possible to produce components with better wear properties than found in today’s wear parts
