Elastic And Thermal Properties Of Cementite

2. cementite: this is a definite carbide of iron (fe 3 c) which is extremely hard, being harder than ordinary hardened steel or glass. cementite increases generally with the proportion of carbon present, and the hardness and also the brittleness of cast iron is believed to be due to this substance.
