Development of Novel Functional Graded Transition Joints for Improving the Creep Strength of Dissimilar Metal Welds in Nuclear Applications – Lehigh University
CX(s) Applied: B3.6
Date: 41869
Location(s): Pennsylvania
Offices(s): Nuclear Energy
The objectives of Lehigh University research is to: 1) Develop design and processing methods for fabricating novel Graded Transition Joints (GTJs) that eliminate failures that occur due to enhanced carbon diffusion and high thermal stresses, 2) Establish a database of creep life and improved creep life models of GTJs that are supported by new techniques for measuring localized strain in the presence of composition and microstructure gradients, and 3) Apply this information to initiate code acceptance by the American Society of Mechanical Engineers (ASME) for use of GTJs in the VHTR application.
