In Situ Characterization of 17-4PH Stainless Steel by Small-Angle Neutron Scattering. [PDF]
Materials (Basel), 2023 17-4PH martensitic steel is usually used as valve stems in nuclear power plants and it suffers from thermal aging embrittlement due to long-time service in a high-temperature and high-pressure environment. Here, we characterized the evolution of microstructures at the nano-scale in 17-4PH steel by in situ small-angle neutron scattering (SANS) with a ...
