Abstract (en)
[origin: EP0149210A2] Very high strengths on the one hand and advantageous ductile properties on the other hand are to be obtained by the process. In a first stage, the iron-based alloys are quenched and atomised in such a way that the predominant quantity of the resulting powder particles is obtained with a diameter of less than 30 mu m and that, in the second stage, the powder particles thus obtained are subjected to a thermomechanical compacting treatment.
