On the afternoon of November 11, Beihang University hosted an academic lecture titled "New Advances in Additive Manufacturing-Based Design and Manufacturing of Aerospace Alloys," delivered by Lu Jian, Chair Professor at City University of Hong Kong and Academician of the French National Academy of Technologies. The lecture covered the process characteristics of additive manufacturing, metamaterial design, and artificial intelligence integration, systematically introducing typical defect control strategies and the principles of material property regulation, with a focus on progress in the design, manufacturing, and validation of ultra-high specific strength titanium alloys, including their application potential in aerospace and the low-altitude economy. Research interest in aerospace alloy additive manufacturing remains strong in academia, and the process-property relationship is a fundamental research theme underlying the application of superalloy and titanium alloy powders. For powder buyers, the validation of new grades such as ultra-high specific strength titanium alloys will drive demand for specialty titanium powders, and it is worth tracking their published data and powder grade requirements.
