Monash University in Australia, together with the Institute of Metals, Chinese Academy of Sciences, and the University of Shanghai for Science and Technology jointly developed and manufactured a nano-super-twinned titanium alloy, which is the 3D printing metal with the highest strength-to-weight ratio so far. Metallic materials provide a strong foundation for the growth of industries in areas such as aerospace, energy, and biomedicine.
Through additive manufacturing technology, researchers use thermal cycles and rapid solidification to achieve nano-super-twinned microstructures, produce high-strength and thermally stable titanium alloys, and overcome problems that require complex casting and thermomechanical processing. The findings provide a completely new approach to precipitation strengthening in commercial alloys. After a simple post-heat treatment of commercial titanium alloys, elongation and tensile strength of 1600 MPa can be obtained, which can be used to produce metals with complex shapes. part.
