The improvement of the material properties and simultaneous reduction of the production time are of a great interest in manufacturing of lightweight metal products. Here, the material properties of the final product are directly relatedto the development of the materials microstructure during the production line. The plastic deformation as well as the heat treatment cause significant changes of the materials microstructure. Consequently, the most important mechanical material properties, e.g. the strength or formability are directly affected.

In order to construct the cost- and time-efficient production processes and thereby to be able to manufacture the products with specific material properties, a deep going understanding of the production process is needed. Since the industrial investigations are costly, numerical simulations of the production process show a great potential for improving the understanding of underlying mechanisms and an efficient design of production processes.

The LKR Leichtmetallkompetenzzentrum Ranshofen GmbH has intensively worked during the last years on the prediction of the microstructure development in various process steps. In order to develop an approach a deep going understanding of the fundamental mechanisms at different length scale levels, from a nanoscale level through a microscale and mesoscale level up to a macroscale level (the level of a real product size) is required. The scientists at LKR masterthe corresponding simulation techniquesandfor the validation of simulation results they refer to the long-standing expertise of the LKR Leichtmetallkompetenzzentrum Ranshofen GmbH on the material characterization.
