## Abstract This paper describes the development and evaluation of thixoformable AlβLiβMgβbased alloys performed at the collaborative research center SFB 289, RWTH Aachen. Scandium and zirconium were added to AlLi2.1Mg5.5 (A1420) with the aid of DoE (Design of Experiments), and precursor billets we
Two different ceramic tool concepts for the semi-solid processing (Thixoforming) of steel alloys are presented. Materials selection is adapted to forming technology (Thixoforging, Thixoextrusion), preset die temperature, and resulting process conditions. Gas-pressure sintered silicon nitride (Si 3 N
