英文摘要	The nanostructure white cast irons without expensive elements were prepared by aluminothermic reaction, the effect of carbon content on its microstructures and mechanical properties was studied by XRD, OM, SEM, tension and compression test. The results show that, the white cast irons consist of pearlite with different shapes and cementite, the lamellar pearlite decreases and granular pearlite increases with increasing the carbon content. The average lamellar spacing of the pearlite phase is 165, 231 and 250 nm, respectively. With increasing carbon content, the vickers hardness of nanostructure white cast iron is 552, 577 and 575 HV, compressive strength is 2224, 2460 and 2220 MPa, and tensile strength is 383, 416 and 245 MPa, respectively, which are all first increases and then decreases with increasing carbon content; the elongation rate is 3%, 2.5% and 1%. The mechanical properties of nanostructure white cast iron without expensive alloying elements are the same to Ni-Hard2 cast iron.
