摘要

Abstract

In this paper,AZ91-Ti cross composites with bionic bone structure were prepared by powder metallurgy combined with pressureless infiltration technology,which achieved the simultaneous im-provement of strength and fracture toughness.Microscopic tests show that the Ti phase is continuously distributed and exhibits a specific bionic skeleton structure,and the Mg phase is interwoven into the connected pores of the Ti skeleton.The serrated Al2Ti phase is formed at the AZ91-Ti interface,which enhances the interfacial bonding strength.The mechanical tests show that the 50vol％AZ91-Ti cross-composite has the best mechanical properties.The yield strength,tensile strength and fracture tough-ness are 383 MPa±3.5 MPa,489 MPa±4.9 MPa and 36.2 MPa·m0.5,respectively.The improvement of the strength of the composite is due to the load effect of the high bionic Ti skeleton and the excellent in-terface bonding.The toughening behavior of the composites comes from the crack winding caused by the Ti skeleton bionic structure and the energy dissipation of the Ti phase extraction.
