Abstract (en)

[origin: WO8501962A1] A white cast iron having toughness, high tensile strength and abrasion resistance containing 0.01% to 4.0% boron in an iron-carbon alloy with the carbides in the form of globules and of an average size less than 4 microns. This white cast iron is produced by incorporating the boron in the composition to form a melt, super cooling the melt while liquid to at least 5?oF below the equilibrium solidification temperature between 2200?oF to 2400?oF and then solidifying the melt to produce the globules of carbides uniformly dispersed and having a size much smaller than the size of the carbide particles of conventional cast iron.
