Purpose and goal

The Project set out to obtain robust physical data on the hot forming process for use in improving the quality of finite element simulations. New information was obtained on the microstructure and processing of pressing hardening steels, along with information on the thermophysical and thermoelastic properties of tools and sheet materials. A number of new and novel laboratory and semi-industrial scale test methods were developed which yielding new information on friction in the hot forming process, as well as heat transfer and formability of sheet steels at elevated temperatures.

Results and expected effects

A catalogue of physical and material data has been assembled on key technical features of the hot stamping process covering: - Microstructure and phase transformations in sheet steels - The structure of Al-Si coatings using in hot forming steels - Friction coefficients between tool and sheet - Temperature and heat transfer during stamping - Thermophysical properties of sheet and tool materials

Approach and implementation

The industrial partners involved in the consortium are integrating this data and the knowledge into their finite element and process design models and workflows. The consortium plans to present key results from the project at several national/international Conferences during 2015.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
