Semi-solid processing and its as yet unexplored potential

Popis výsledku v původním jazyce

Thanks to the available advanced control technology, manufacturing processes which have been described in the past but their hidden potential remained untapped are now continuing to be developed. As a result, even conventional materials which have been around for years can be manipulated to obtain unusual microstructures with specific mechanical and physical properties. Semi-solid processing belongs to the above-described group: it had been studied in the past but, due to complicated process control, it gradually lost its appeal. However, advanced techniques of temperature field control enable engineers to control this complex process thixoforming. As it focuses on very small-size products, it offers very steep heating curves and extremely high solidification and cooling rates, when compared to ledeburitic tool steel. After the optimum processing conditons were found, additional material were tired, ranging from low-carbon microalloyed steel through medium-alloy steels to high-alloy tool steels. The microstrucure evolution upon the mini-consisted of more than 90% of austenite and chromium carbides. Semi-solid processing of a steel with a high vanadium content led to a microstructure comprising martensitic-ustenitic (MA) matrix and globular vanadium carbides. In the low-alloy steel, martensitic microstructure wqs obtained.
