    CAE Seminar- Additive Manufacturing: Laser Directed Energy Deposition of CuNiTi Ternary Alloy, Hydrogel-Infused Additive Manufacturing, and Continuous Fiber Composites- Anil Saigal

    McCormick - Civil and Environmental Engineering (CEE)

    11:00 AM A230, Technological Institute

    EVENT DETAILS

    Abstract: Additive manufacturing (AM) of materials can enable rapid development of functional parts of complex geometry, with potential applications in the aerospace, automotive, electronic packaging, and biomedical fields. Three AM techniques are presented. First, Cu-Ni premixed elemental powders are deposited on the pure Ti by laser-directed energy deposition (LDED) using a novel method of extracting Ti from the substrate through melt pool convection. The X-ray diffraction (XRD) pattern and microstructure image reveal the presence of NiTi binary (B2) and Ti2CuNi ternary (B19) hard phases and equiaxed dendritic morphology, respectively, demonstrating ternary alloy coating formation. The coating has a hardness of 550 Hv, which is thrice that of the substrate, and wear resistance that is (80%) higher. Second, the Hydrogel-Infusion Additive Manufacturing (HIAM) process involves 3D printing a polyethylene oxide (PEO) photo-resin using vat polymerization, immersing the polymer in a metal salt solution (Silver nitrate) which allows ionized metal cations to bond to the polymer backbone, followed by calcination/reduction at 500°C to combust the polymer leaving a metal oxide (AgO) / metal product (Ag) that maintains a scaled-down version of the complex as-printed architecture (spring). Finally, the thermal conductivity of additively manufactured continuous fiber composites for applications where heat dissipation is an important consideration, is presented. Bio: Anil Saigal received his B. Tech. In Mechanical Engineering from Indian Institute of Technology Bombay and his M.S. And Ph.D from the Georgia Institute of Technology. He is a Fellow of ASME. He is currently a Professor of Mechanical Engineering at Tufts University and has served as the Chair of the Department.
