Since the first research works in the end of 1980s on the semi-solid forming of steel, thisprocess has presented a great interest and a real industrial potential. Several research teams, all overthe world, have shown the feasibility of such a process. Working on the parameters which have aninfluence on the process, they pointed out the "technical locks" which must be overcome to allowindustrialization of the process. A first and perhaps most important difficulty is the reliability of theforming tools in an industrial production context. Much work has therefore been devoted to identifyways to increase tools life. A second important point is the possibility to obtain soundmicrostructure and satisfactory mechanical properties. This paper is a state of the art review on thesubject of the thixoforming of steel, restricted to forming of semi-solid reheated steel. Semi-solidforming process carried out after partial solidification are therefore not covered. The readerinterested in such processes may refer to the review recently published by Hirt et al. [1].The present review considers, in turn, the different steps of an hypothetical production line and theirparticular challenges, from the raw material to the final product
