日期:2017 年 12 月 08 日 ( 星期五)
Time:4:00 pm – 5:30 pm
Venue:AG710

Abstract:

Through laser solid forming additive manufacturing (LAM), the parts with complicated geometry can be free-form near-net shaped rapidly without using the mold, meantime, the mechanical properties of the LAMed parts is equivalent to those of the wrought. These features make LAM be a viable and promising manufacturing technology for aviation industries, especially for the manufacturing of large components. In present work, the current applications of LAM technology on the aviation field are reviewed.The typical technical characteristics of LAM technology, the microstructure and mechanical properties of typical LAMed parts are analyzed, the effect of scanning pattern on the thermal/stress field during LAM of large components is introduced. Finally, the problems for the applications of LAM technology on the aviation field are discussed.

Bio-sketch:

Prof. Dr. Xin Lin is Director of Key Laboratory of Metal High Performance Additive Manufacturing and Innovative Design, Ministry of Industry and Information Technology (MIIT), and Deputy Director of the State Key Laboratory of Solidification Processing China, Northwestern Polytechnical University (NPU), China. His areas of research include metal additive manufacturing (AM) and solidification. He received his PhD from NPU in 2000 and worked as a postdoctoral fellow at The Hong Kong Polytechnic University. He holds 15 Chinese patents and has published two monographs and over 400 articles in journals, such as Acta Mater., J. Crystal Growth, Scripta Materialia, Metallurgical and Materials Transactions A, Journal of Applied Physics, and Materials Science & Engineering A and B. His research on laser AM has found commercial applications in aviation, aerospace, power, energy and medical sectors, and met the urgent needs for high-performance, light-weighting, high integration and high precision fabrication tin these high-tech fields. He was appointed as a New Century Excellent Talent by the Ministry of Education China in 2006, and awarded a Newton Fellowship by Royal Society in the UK in 2015.
