Abstract

Fe83C17 alloy melt can be cast readily into white cast iron. It is brittle, with a compressive strength of ~1300 MPa. By a fluxing technique, a Fe83C17 melt can be quenched into a crystalline solid of ultrafine networklike microstructure, with a hardness value of ~536 HV, a yield strength of ~2000 MPa, and a strain to failure of about 18 pct. In particular, a cube made of Fe83C17 network alloy can be compressed to a disk.
