Title (EN) IRON-BASED CASTING ALLOY AND PROCESS FOR MAKING SAME
(FR) ALLIAGE DE MOULAGE A BASE DE FER ET PROCEDE DE FABRICATION CORRESPONDANT
Abstract:
(EN) An iron-based casting alloy and a process for making the alloy are provided by combining an iron-carbon-chromium system with primary carbides of vanadium, niobium, titanium, or combinations thereof without any eutectic carbides of vanadium, niobium and titanium. Eutectic chromium carbides (M7C3) are also formed without any primary chromium carbides. Proeutectic austenite can also be formed in the alloy.
(FR) L'invention concerne un alliage de moulage à base de fer et son procédé de fabrication, lequel consiste à combiner un système fer-carbone-chrome à des carbures primaires de vanadium, niobium, titane, ou des combinaisons de ces métaux sans formation de carbures eutectiques de vanadium, de niobium, ou de titane. Les carbures de chrome eutectiques (M7C3) sont également préparés sans formation de carbures de chrome primaires. Des austénites proeutectiques peuvent également être formés dans cet alliage.
