Nanaostructure-dendrite Ti44Cu46Co4Zr6 composite with excellent mechanical properties

摘要

New bulk nanostructure-dendrite Ti44Cu46Co4Zr6 composite with excellent mechanical properties has been fabricated by using copper molder casting through systematic alloy design from binary Ti50Cu50.The results showed that the micro-scaled β-Ti(M) solid solution embedding on the nanostructured matrix,which resulted in the excellent mechanical properties:high fracture strength (σf=2278 MPa) and good ductility (εp =9.01％) under quasi-static compression.
