Kacher Receives DOE Basic Energy Science Early Career Award
Assistant Professor Josh Kacher was awarded the DOE Basic Energy Science Early Career Award for his project titled "Fundamental Study of Fatigue Crack Initiation at Grain and Twin Boundaries in Austenitic Stainless Steel." Kacher's research seeks to understand the evolution of the defect state leading to fatigue crack initiation in austenitic stainless steels and how this process relates to the surrounding microstructure. To access this information, novel in situ scanning and transmission electron microscopy deformation experiments capable of resolving the evolution of the local defect state and the accompanying stress fields will be developed. This information is needed to guide the development of novel, fatigue resistant materials, and to better predict the lifetime and reliability of materials currently in use. The Early Career Research Program supports the development of individual research programs of outstanding scientists early in their careers and stimulates research careers in the disciplines supported by the DOE Office of Science. The 59 selectees for fiscal year 2017 were chosen based on peer review of about 700 proposals.
