Ronald Scattergood joined the NCSU faculty as a Professor in 1981. His research is aimed at gaining fundamental understanding of the mechanical behavior of materials. His earlier research interests at NCSU include solid particle erosion of metals and ceramics and toughening mechanisms. A new method for for evaluating R-curves at small crack lengths was developed. He was one of the the founding group of researchers that initiated the Precision Engineering Center at NCSU. His reseach there included precision machining of brittle materials and later wear of diamond tools for machining steels. His more recent research is on the mechanical properties and microstructure interactions in nanocrystalline metals and alloys. Current research involves high-temperature stablization mechanisms for nanocrystalline alloy microstructures. A thermodynamic-base model for nano-grain size stabilization was developed as part of this research.
