Scientific Breakthrough
We design a novel non-equiatomic Ti-rich medium entropy alloys by CALPHAD. Cast Ti-65 alloys demonstrate tensile yield strength of 950 MPaductility of 30. Heterogeneous structured Ti-65 alloys demonstrate extraordinary tensile properties (YS: 1240, TS: 1510MPa, EL: 25). Some of outstanding hetero-structured works in world class journals reached the specific strength of 144 MPa·cm3/g, ductility of 25 (Science)254 MPa·cm3/g, 13 (Science).This novel lightweight heterogeneous structured Ti-65 alloy possesses ultra-high specific strength of 247 MPa·cm3/g a excellent ductility of 25.
Industrial Applicability
Lightweight materials with high strengthductility are the goals for industrial application. This novel lightweight (5 g/cm3) heterogeneous structured Ti-65 alloy possesses ultra-high specific strength of 247 MPa·cm3/gductility of 25. The extraordinary properties of this alloy undoubtedly dominate lightweight materials community.We produced the large dimension Ti-65 ingotsface of club head in cooperation with Fusheng to demonstrate the promising potential on commercial commodities. This work will focus on the aerospace areas, transportationhigh additional valued products.
