Abstract (en)
[origin: EP0587960A1] The process makes possible the production of iron aluminide materials comprising an Fe3Al-based alloy with 18-35% of Al, with 3-15% of Cr, with 0.2-0.5% of B and/or C, and with a total of 0-8% of the following alloy additives: Mo, Nb, Zr, Y and/or V, and also Fe as predominant remainder. According to the invention, additives are added to the melt of a known alloy from which dispersed crystallites, so-called dispersoids, form and which are, thanks to good wettability, bedded into the monocrystalline phase on solidification. A fine-grained microstructure can be generated from the solid alloy by hot rolling at a temperature between 650 and 1000 DEG C. <IMAGE>
