Die Soldering and the Influence of Alloying Elements
Marius Kohlhepp talks in the lecture about the formation of die soldering and the influence of alloying elements on the intermetallic interface.
Die soldering of die castings is a serious problem in the aluminum casting industry. The precise mechanism, the influence of the alloy composition, and the options for prevention have not yet been fully elaborated. A well-established solution for alloys with low iron content is the addition of manganese. However, up to 0.8 wt.% is necessary, which increases the amount of brittle phases in the material and consequently reduces ductility. This presentation shows the results from immersion tests with 1.2343 tool steel and a hypoeutectic AlSi-alloy with Mn, Mo, and Cr additions to systematically investigate the formation of die soldering, how to effectively prevent it and simultaneously maintain high mechanical properties.
