This paper presents the mathematical model ALSPEN, in which the thermally induced strains and stresses which develop during direct chill (DC) semicontinuous casting of aluminium billets are calculated by a finite-element method. The metal is assumed

Solar cells can have various shunts with various origins and current-temperature characteristics. A solar cell with a local ohmic shunt can heat up during partial shadow conditions due to reverse current through the shunt. Depending on the resulting

The present work presents a 3D thermo-mechanical model and its application to the casting of square multi-crystalline silicon ingots. Stresses and deformations in the ingot are the results of the combined effects of thermal contractions and mechanica

When applying the Hydro variant (Hycast Gas Cushion) of the Showa Denko gas slip technology for casting extrusion ingots of 7xxx alloys surface cracks occasionally occurred. Especially one alloy with 0.3 wt.% Cu caused problems. In order to identify

Wire rod is produced by hot-rolling a bar of metal coming from a wheel/belt continuous casting process. This kind of process, e.g. Properzi, is an elaborate process in which the molten metal is poured in a cooled rotating mould formed by the groove o

Direct chill (DC) casting of high strength 7xxx series aluminum alloys is difficult mainly due to solidification cracking (hot cracks) and solid state cracking (cold cracks). Poor thermal properties along with extreme brittleness in the as-cast condi
