Abstract: The disclosure provides a method of making an iron matrix composite. A Fe—Ni—P composite powder having a particle size of one to two micrometers and a Fe—N powder having a particle size of 100 to 250 nanometers are used as the raw material. The size and axial displacement of pressing heads of a graphite mold are controlled to realize the control of the porosity of porous iron. The composite produced comprises two surface layers of a Fe—Ni—P alloy and an intermediate layer of porous iron having a porosity of 14 to 39%. The method enables a reduced weight of the Fe—Ni—P alloy and enables shock absorption and damping properties to be imparted to the composite. In addition, an optional subsequent deep cryogenic treatment allows the Fe—Ni—P alloy to be subjected to phase transition from a metastable gamma-phase to an alpha-phase, thereby substantially improving the hardness and strength thereof.
