... Abstract Malleable iron, like ductile iron, possesses considerable ductility and toughness because of its combination of nodular graphite and low-carbon metallic matrix. There are two basic types of malleable iron: blackheart and whiteheart. This article focuses on the blackheart malleable iron...

... to produce temper carbon involves heating a white cast iron for an extended period of time (up to about 60 h) at a temperature of 960 °C (1760 °F). Most of the malleable iron that is produced by this technique is called blackheart malleable iron, while some malleable iron (called whiteheart malleable iron...
