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 ...

Simple multiaxial tests to assess dynamic ductility of 17-4PH
Materials Research Proceedings, 2023 Abstract. To investigate material ductility, the use of simple multiaxial specimens which can be tested through a common tensile machine or by a Split Hopkinson bar facility would allow avoiding the use of more complex equipment to induce different stress states in the investigated material.
