Alloy development for high pressure die casting

Despite of the established foundry practice of several Al-Mg-Si-Mn and Al-Zn-Mg casting alloys subjected to high pressure die casting, only little research was done either on structure formation or strengthening mechanisms of these alloys and mechanical properties that can be achieved after additional alloying. As cast conditions of AlMg5Si2Mn alloyed by Zn, Sc, Cr and Zr are investigated paying attention to precipitates formed in solid solution matrix prior to heat treatment and changes of mechanical properties from as-cast state to age hardened state.Another focus is the adaptation and the development of alloys for electrotechnical applications.
