Abstract

During the solidification of continuously cast ingots, thermally induced stresses generate casting errors as 
hot cracks, bending or residual stresses. Contraction mechanism and shrinkage due to solidification of the 
alloy which is in a pasty state induce occurrence of the above mentioned defects. Simulation of thermo - 
mechanical properties of ALMgSi-alloys in zones of primary and secondary cooling was performed using 
software MAGMA 5.2.0. The simulation results over the length and cross section of ingots, showing the 
development of local stresses during solidification in the area close to solidus and residual stresses after 
the casting.
