NEUP CINR-19-17206: Laser Additive Manufacturing of Grade 91 Steel for Affordable Nuclear Reactor Components

The primary goal of the proposed work is to determine the feasibility of laser additive manufacturing (LAM) for producing reactor components of a ferritic/martensitic steel (Grade 91) with an engineered microstructure. We propose to tailor the LAM process parameters to provide in-situ tempering of the Martensite in previously deposited layers. Using this approach, the component will have the desired combination of properties and will require no further heat-treatment before service, at lower cos
