This book introduces readers to titanium matrix composites (TMCs) with novel network microstructures. The bottleneck problem of extreme brittleness and low strengthening effect surrounding TMCs fabricated by means of powder metallurgy has recently been solved by designing network microstructures, which yield both high strength and superior ductility. As such, network structured TMCs will increasingly offer materials characterized by low weight, high strength, high temperature resistance and superior deformability. The book systematically addresses the design, fabrication, microstructure, properties, modification, and toughening mechanisms of these composites, which will help us find innovative solutions to a range of current and future engineering problems.

Dr. Lujun Huang received his M.S. (2007) and Ph.D. (2011) in Materials Science at Harbin Institute of Technology, China. He is currently a full professor at the State Key Laboratory of Advanced Welding and Joining and School of Materials Science and Engineering at Harbin Institute of Technology. His research focuses on the design, fabrication, tailoring, modification, microstructure, properties, deformation and heat treatment of metal matrix composites, especially titanium matrix composites (TMCs). He has published more than 75 peer-reviewed research papers in prestigious international and national journals, and has received several awards including Heilongjiang Province's First Class and Second Class Award of Science and Technology, and Harbin Institute of Technology's Excellent Ph.D. Thesis Award.
Dr. Lin Geng received his Ph.D. (1990) in Materials Science at Harbin Institute of Technology, China, where he is currently a full professor at the School of Materials Science and Engineering. His research focuses on the design, fabrication, tailoring, modification, microstructure, properties, deformation and heat treatment of metal matrix composites, including aluminum matrix composites (AMCs), titanium matrix composites (TMCs) and intermetallic matrix composites. He has published more than 350 peer-reviewed research papers in prestigious international and national journals, and has received two Awards of Science and Technology from Heilongjiang Province.
