Abstract: The submitted article deals with the study of casting and solidification of a 12 t ingot made of structural steel 42CrMo4 using numerical simulations in the THERCAST® and MAGMASOFT® software. The possibilities of each individual software in filling and solidification of steel were assessed, including the prediction of ingot defects such as porosity, shrinkage cavities or shrinkage porosities; the proportion of liquid phase, segregation of selected elements and solidification time were also monitored..

Abstract: To explore the feasibility of directly spinning thin-walled components from aged aluminum alloy sheets under rapid laser heating, the laser-assisted spinning process of aged 7075-T6 aluminum alloy was carried out by means of an ellipsoid component shear spinning test. Compared with cold spinning, the critical thinning of the laser-assisted spun component was more than 30 % higher than that of the cold spun component, and the laser-assisted spun component has good geometric accuracy, which indicates that the formability of the 7075-T6 aluminum alloy can significantly be improved with the laser-assisted spinning process.

Abstract: A sheet-forging process is proposed to form thin-walled structures with crossed-ribs. To solve the problem of grid distortion in finite element simulations, an element reconfiguration strategy that combines a stress-strain map solution and element reconstruction is applied, and typical samples with crossed-ribs are designed to verify the accuracy of simulation.

Abstract: Forging tools are exposed to cyclically changing thermo-mechanical stress conditions leading to its failure. Damage phenomena on the tool engraving cannot be entirely avoided by hardening the surface, as this leads to a more brittle behaviour and thus to lower ductility of the material, which can intensify the occurring damage effects.
