Achieving high strength and large ductility via Zr-rich stripes in Ti-15Zr alloy

• Ti-15Zr alloy prepared by powder metallurgy includes ? single-phase with Zr-rich stripes. The has a good combination of strength and ductility. High the is ascribed to hindrance effect Zr Good ductility attributed occurrence slip transmission across microstructures mechanical properties (wt.%) hot extrusion were investigated. comprised stripes distributed at both intra- inter-granular. tensile yield ? 773 MPa, an engineering ultimate 874 total elongation 28.6%. stripes, since they could hinder movement dislocations strengthen grain boundaries but cannot limit their completely, namely, occur them. Our findings provide new way titanium alloys without sacrificing
