This book presents the melt pool monitored-laser additive manufacturing (MPMed-LAM) technology for enhancing forming quality and mechanical performance of key metalic components. Despite progress in metal additive manufacturing (AM) since the 1970s, a large number of challenges remain in synergic controlling both shape and performance due to thermal stress-induced defects and metallurgical flaws. The book reviews key research on melt pool monitoring, forming quality control, microstructure evolution, and mechanical performance in laser additive manufacturing (LAM), providing a foundation for…mehr

Produktbeschreibung
This book presents the melt pool monitored-laser additive manufacturing (MPMed-LAM) technology for enhancing forming quality and mechanical performance of key metalic components. Despite progress in metal additive manufacturing (AM) since the 1970s, a large number of challenges remain in synergic controlling both shape and performance due to thermal stress-induced defects and metallurgical flaws. The book reviews key research on melt pool monitoring, forming quality control, microstructure evolution, and mechanical performance in laser additive manufacturing (LAM), providing a foundation for understanding MPMed-LAM of some kinds of metallic components. Divided into four parts, it covers the background, thermal modeling, and detailed analysis of defects, microstructure, dimensional accuracy, corrosion, and mechanical properties of metallic components made via MPMed-LAM. Aimed at professionals in mechanical engineering and materials science-particularly in aero-engine applications, it offers some important insights into the mechanisms and future development potential of this advanced technology.
Autorenporträt
Prof. Kaiyu Luo is currently working at the School of Mechanical Engineering at Jiangsu University of China. She has focused on the laser shock peening (LSP) process and investigation of microstructural evolution and corrosion resistances. She had published 20 invention patents and more than 150 papers in peer-reviewed international journals, including International Journal of Machine Tools and Manufacturing, Acta Materialia, International Journal of Plasticity, Corrosion Science, Materials & Design, International Journal of Fatigue, Applied Surface Science, etc., which have received over 3000 citations with an H-index of 29 according to the Scopus database. Dr. Youyu Su received her Ph.D. in Mechanical Engineering from Jiangsu University under the supervision of Prof. Kaiyu Luo. She has focused on laser additive manufacturing (LAM) and melt pool monitoring (MPM) to improve the forming quality of laser directed energy deposition (LDED) for seven years. She has published 13 papers relating to LAM and MPM in international journals, including Additive Manufacturing, International Journal of Mechanical Sciences, Journal of Manufacturing Processes, Materials Science & Engineering A, etc. Prof. Jinzhong Lu is an internationally well-known professor in laser shock peening (LSP) and laser additive manufacturing (LAM). He first proposed LSP-induced surface nano-crystallisation of metallic materials, first built a relationship between the LSP-induced strain rate and the local microstructure, and developed microstructural evolutions of FCC, HCP, and BCC materials. He has published 20 invention patents and more than 210 papers relating to LSP and LAM in international journals, including International Journal of Machine Tools and Manufacturing, Acta Materialia, International Journal of Plasticity, Additive Manufacturing, Corrosion Science, etc., which have received over 6100 citations. His contributions in fundamental research and experimental data provide useful information for researchers and engineers in LSP and LAM.
