Abstract:xTiC/FeMnCu(x=2.5, 5, 7.5, 10, vol%) composites were fabricated by vacuum induction melting and then annealed. X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive spectrum (EDS) were used to analyze the phase constitution and microstructure, and the tensile properties of the samples were investigated by the universal tensile testing machine. The results show that the xTiC/FeMnCu(x=2.5, 5, 7.5, 10, vol%) composites exhibit a biphasic face-centred cubic structure. With the increase in x value, the matrix structure of the composites is significantly refined and the tensile strength gradually increases, which is due to the combined effect of fine grain strengthening, thermal mismatch strengthening and Orowan strengthening. After 10TiC/FeMnCu is annealed at 600 °C for 4 h and 800 °C for 4 h, the structure does not change significantly, and carbides are precipitated in the matrix. The tensile strength of the sample increases but the elongation decreases slightly.
