Abstract

Foreliggende oppfinnelse omhandler en ny type kornforfinere for stål, i form av et partikulært komposittmateriale, som inneholder en stort volumandel av spesiallagede dispergerte partikler, i den hensikt å fungere som potente heterogene nukleeringssteder for jernkrystaller under størkning og påfølgende termomekanisk behandling av stålet. Materialet omfatter en sammensetning av partikler av XaSb eller XaOb og element(ene) X, hvor X er ett eller flere elementer valgt fra gruppen Ce, La, Pr, Nd, Y, Ti, Al, Zr, Ca, Ba, Sr, Mg, Si, Mn, Cr, V, B, Nb, Mo og Fe, og S er svovel, (O er oksygen), hvor materialet i tillegg omfatter oksygen, svovel, karbon og nitrogen, hvor svovel (eller oksygen) -innholdet er mellom 2 og 30 vektprosent av materialet, mens det totale innholdet av oksygen (eller svovel), karbon og nitrogen og de andre elementene valgt fra gruppe X er mellom 98 og 70 vektprosent av materialet, og nevnte materiale inneholder en høy volumandel av fint dispergerte XaSb eller XaOb partikler inneholdt i en metallmatrise X. Oppfinnelsen omhandler videre fremgangsmåter for fremstilling og bruk av komposittmaterialet.
