Monash University, Australia, the Institute of Metal Research, the Chinese Academy of Sciences, and the University of Shanghai for Science and Technology jointly developed a nano-super-twinned titanium alloy, which is the 3D printing metal with the highest strength-to-weight ratio so far. Metallic materials provide the foundation for advancing industries in fields such as aerospace, energy, and biomedicine. The related results were published in "Nature Materials".
Through additive manufacturing technology, researchers use thermal cycling and rapid solidification to achieve nano-super-twinned microstructures to produce high-strength and thermally stable titanium alloys that overcome the need for complex casting and thermomechanical processing. The findings provide an entirely new approach to precipitation strengthening in commercial alloys, achieving 1600 MPa elongation and tensile strength after a simple post-heat treatment of commercial titanium alloys for the production of metals with complex shapes part.
