Title: Innovations in Nanotwinned Alloys by Jessica Krogstad
Introduction
Jessica Krogstad is an accomplished inventor based in Champaign, IL (US). She has made significant contributions to the field of materials science, particularly in the development of advanced metallic alloys. Her innovative work focuses on the synthesis of nickel-molybdenum-tungsten films and coatings, which have promising applications in next-generation technologies.
Latest Patents
Jessica holds a patent for a "Method of depositing nanotwinned nickel-molybdenum-tungsten alloys." This invention is directed towards the synthesis of metallic films and coatings using direct current sputter deposition. The resulting films are fully-dense, crystallographically textured, and filled with nano-scale faults and twins. These films exhibit linear-elastic mechanical behavior and tensile strengths exceeding 2.5 GPa, which is unprecedented for materials compatible with wafer-level device fabrication processes. The ultra-high strength is attributed to solid solution strengthening and the presence of dense nano-scale faults and twins. Additionally, these films demonstrate excellent thermal and mechanical stability, high density, low coefficient of thermal expansion (CTE), and desirable electrical properties for metal MEMS applications. When deposited as coatings, they provide protection against friction and wear. The films can also be heat treated to modify their internal microstructure and mechanical properties, achieving a balance of strength and toughness.
