Abstract [en]

This is a part report in the Swerea KIMAB AB project 222009 Modflat. The experimental result presented here can be used as materials data for the FEM software Sysweld where the quenching operation is simulated. In this work thermal and metallurgical properties and temperature dependent mechanical strengths has been determined for the Ruukki material here called Steel 1 with a thickness of 10 mm. The metallurgical properties that have been determined are heat conductivity (measured up to 500°C), enthalpy per phase (calculated by ThermoCalc), thermal expansion (measured by dilatometer), volume changes during phase transformation (measured by dilatometer) The mechanical properties that have been determined are Young’s modulus, yield stress and deformation hardening for different structures at different temperatures. The mechanical properties were measured by hot tensile tests and compressions tests. Sysweld is used as simulation software for the quenching simulations and consequently the material properties that are presented on a format that is easily implemented in Sysweld. The material properties are divided into the hot rolled structure, the austenitic phase and the martensitic structure.
