Introduction Particle-reinforced steel matrix composite has been extensively studied as materials bearing high hardness, exceptional strength and elastic modulus[1-3].When hard SiC particles were incorporated in steel matrix, gains from both ceramic phase and steel matrix could improve the mechanical properties, such as strength and wear resistance of the steel matrix[4-5].
The uniformity of composing particles greatly affected the properties of composite materials[8-10].
