Prof. J.K.Chen (陳貞光), received his PhD in Materials Engineering Science from Virginia Polytechnic Institute and State University (Virginia Tech) in 1995. After working for 10 years in the industry, he joined Dept. Materials and Mineral Resources Engineering of National Taipei University of Technology in 2005. He has been working closely with the industry on development of applied metals processes. His recent work emphasizes on additive manufacturing and power metallurgy of various alloys. He has also been working on development of metal matrix composites for thermal management in HPC.
Development of Sintering Systems and DFT Simulations in TiB₂ Ceramics

Powder Metallurgy And Additive Manufacturing/TBA
Titanium diboride (TiB₂) is a promising ultra-high-temperature ceramic for aerospace and defense applications due to its high hardness, thermal stability, and electrical conductivity; however, poor sinterability and intrinsic brittleness limit its practical use. In this work, a series of reactive sintering strategy was developed to fabricate TiB₂-(MoB₂,NbB₂) ceramics. Complementary density functional theory (DFT) simulations were conducted on Ti1-xMxB2 (M = Mo, Nb) solid solutions to predict phase stability, bonding characteristics, and mechanical behavior. Results revealed that equiatomic compositions (x=0.5) offer optimal trade-offs between stiffness and toughness, with dynamic stability, and enhanced ductility. DFT calculations confirm that the solution enhances metallic bonding character within the inherently covalent TiB₂ lattice, contributing to improved toughness and ductility.
