| Abstract |
Since the first research works in the end of 1980s on the semi-solid forming of steel, this
process has presented a great interest and a real industrial potential. Several research teams, all over
the world, have shown the feasibility of such a process. Working on the parameters which have an
influence on the process, they pointed out the "technical locks" which must be overcome to allow
industrialization of the process. A first and perhaps most important difficulty is the reliability of the
forming tools in an industrial production context. Much work has therefore been devoted to identify
ways to increase tools life. A second important point is the possibility to obtain sound
microstructure and satisfactory mechanical properties. This paper is a state of the art review on the
subject of the thixoforming of steel, restricted to forming of semi-solid reheated steel. Semi-solid
forming process carried out after partial solidification are therefore not covered. The reader
interested 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 their
particular challenges, from the raw material to the final product. |
