Presentation Abstract

The increasing demands for materials serving under extreme environments calfor the development ofemerging classes of metal alloys with increasinglcomplex compositions, However, synthesis and processing ofcomplex alloys yiatraditionalroutes are challenging, Additive manufacturing, also called 3D printingis a disruptive technology for creating materials and components in a single printHarnessing the vast compositional space of complex alloys and the far-fromequilibrium processing conditions (e.g., large thermal gradients and high coolingrates)of additive manufacturing provides a paradigm-shifting pathway fo.material design. In this talk, I will present the potential ofutilizing laser additivemanufacturing and direct ink writing to produce metal alloys with engineeredstructural hierarchy across multiple length scales. These unigue microstructuresgive rise to exceptional mechanical and functional properties that extend falbeyond those accessible by conventional manufacturing. In addition, l will discussthe abundant opportunities enabled by additive manufacturing for high-throughputmaterials discovery to accelerate the pace of future materials search for a widerange of applications in aerospace, biomedical, and renewable energy.
