Forming Experiments and Die Development for Processing Steels in the Semi-Solid Range
The industrial start-up of mass production for first components from aluminium or magnesium alloys especially for the automobile and electronic industry - shows the potential that is attributed to the semi-solid process. As result of the big spectrum of adjustable mechanical properties, steel is widespread in many fields and a substitution by other materials is not practicable in many cases. The net shape or near-net shape production of steel components by semi-solid technology can lead to a significant shortening of the process chain and offers potential for light-weight applications. In forming experiments small components made from the steel grades M2, 100Cr6 und X210CrW12 were produced through a semi-solid lateral extrusion process. Results of joining functional steel parts (screw) with a steel component during thixoforming in one process step are presented. Promising coated and uncoated metallic tool materials are presented and tested during practical use.
