Abstract:

This work describes the processing of different aluminum cast- and wrought alloys in the Cooling-Channel-Process. The investigations take the castability, the microstructural evolution for the SSM-processing and the resulting properties in the test specimen into account. Beside the alloys AlMg5Si2Mn (M59), AlCu4TiMgAg (AF48), AlSi12CuNiMg (SF70), AlSi17Cu4Mg (SF90), AlZnMgCu1,5 (AA7075) the optimization of the alloy AlSi7Mg0,3 (A356) by the addition of magnesium and copper were a main task of the work.
