摘要:
By adding titanium and boron elements in the molten steel whose compositions were 0.10-0.30%C, 0.20-0.50%Si, 0.60-1.20 %Mn and 0.50-1.50 %Cu, particulate-reinforced metal matrix composites (MMCs) were obtained. The reinforced phase and matrix were studied by means of the optical microscopy (OM), the scanning electron microscopy (SEM) and the X-ray diffraction (XRD). Moreover, the mechanical properties and abrasion resistance of steel-based MMCs were measured. The results show that the in-situ reinforced particulates of steel-based MMCs are TiB2 and Fe2B. After heat treatment, the in-situ reinf...
