| Abstract Scope |
Ongoing development of Al-Si cast alloys leads to an increased usage of alloying elements to fulfill different property demands. This new complexity of composition may lead to the formation of various phases, of which some are desired and others unwanted. In the present case, a model Al-Si alloy was developed on a laboratory scale and analyzed. The idea behind the alloy was to reduce die sticking while increasing its mechanical properties by adding the transition metals Cr, Mn, and Mo. Special attention was given to the formation of phases rich in the above mentioned elements. During permanent mold experiments, an unintended formation of a phases rich in the added elements was discovered. Recommendations on how to avoid the formation of this phase are given as well. |
