摘要

Abstract

BSTRACTA heterogeneous (

) titanium alloy with extraordinary tensile properties was prepared. The heterogeneous microstructures

consisting of soft

fiber

and hard (

)

matrix

were achieved by controlling the distribution of

-stabilizing element. The heterogeneous alloy exhibits ultra-high strength of 1634 MPa with reasonable ductility

which is much higher compared to the homogeneous counterpart. The plastic incompatibility of the

fiber

and (

)

matrix

produces hetero-deformation induced (HDI) hardening

which is the main reason for the enhanced strength. Moreover

the

-twining and martensitic transformation are responsible for the good ductility. This work provides a new strategy to achieve superior strength-ductility combination for multi-phase alloys.
