Abstract:
      In this study,the B4C particles reinforced aluminium matrix composite tube with different deformation was first fabricated by spark plasma sintering (SPS) and followed by asynchronous offset spinning. It was found that the B4C particles distributed change from net to relatively homogeneously in the aluminium matrix with the spun deformation increase. The interface between B4C and aluminium was formatted metallurgical bonding due to the discharge was happened lead to the local high temperature existed during SPS processing and the interface was mainly consisted of AlB2 and Al3BC phase. With the deformation increasing, the aluminium grain and B4C size was decrease. But, large size of B4C particles fracture was decrease the fine-grain and particles strengthening function for the tensile strengthening.
