Investigating variation of back stress in 316H during high temperature asymme...
Deformation in polycrystalline material is inhomogeneous. Our previous study using neutron diffraction has shown due to these inhomogeneities, during high temperature cyclic... -
Unstressed lattice parameter studies for weld residual stress determination
This study addresses the need to improve the reliability of measurements of weld residual stress; particularly for the type of welds used within the nuclear power industry. Such... -
Residual stresses in a ring weld specimen after extended creep relaxation
Reheat cracking is a failure mechanism seen in welds fabricated from high temperature creep resistant materials. A new feature test specimen (ring-weld) has been designed to... -
In-situ study of nickel recrystallization using neutron diffraction
The objectives of this project are to: 1) advance in-situ studies of recrystallization kinetics in deformed metals using neutron diffraction. This is new approach which will... -
Lattice strain evolution during uniaxial tension of an engineering steel
In our research program the overall goal is to explore residual stress effects on fracture of engineering steels at high temperatures. Towards this goal, we need to understand... -
Effect of intergranular stress on creep deformation in 316H during high tempe...
Creep lifetime of high temperature power plant materials are significantly affected due to predicted and unpredicted cyclic loading during plant operation. Our previous study... -
Texture memory and variant selection for steel and titanium and zirconium alloys
The proposed experiment will focus on determining the level of texture memory and variant selection on both heating and cooling for steel and titanium and zirconium alloys with...
