Abstract
A test stand for thermal loading of steels was developed for the simulation of die casting of Al products. Special specimens were made which were subjected to automatic immersion into molten Al and a cooling emulsion (water + graphite). At the inside, the specimens were water-cooled. In the course of repeated cycles, the temperature inside the specimens was measured at two different points. A computer program permitted the calculation of temperature, stress and deformation distributions in the specimens. A comparison of the measured and calculated temperatures is shown for two points in the specimen. After 6000 cycles, the surface and the interior of the specimens were examined. The number, length and depth of cracks were determined. It was found that major damages occurred at the specimen edges. The damages included edge rounding, cracks, and material hardening just beneath the surface.
