Rapid solidification laser processing and forming of advanced aeronautical metallic materials

Research progress on rapid solidification laser surface modification of advanced metallic materials, rapid solidification laser cladding for high-temperature wear and corrosion resistant multifunctional intermetallic coatings, and rapid solidification laser additive manufacturing for high performance metallic components was reported. The main contents include laser surface alloying and laser cladding surface modification of titanium alloys, liquid/ solid interface structure and growth mechanisms of typical faceted phase under non-equilibrium rapid solidification conditions, laser rapid forming/manufacturing of high performance titanium and nickel-based alloys, laser constrained melting/forming of refractory metals and intermetallic alloys, and directionally solidified columnar grained titanium alloys.
