High strain rate studies of twinning
Where a material can plastically deform by more than one mechanism, the relative extent to which the various mechanisms operate often depends on the strain rate. Most metals... -
Residual stress measurement across a full-sized 304-stainless steel girth-but...
A full-sized section of 304-stainless steel pipe with a non-stress relieved girth-butt weld has been obtained from a Pressurised Water Reactor. This project will accurately map... -
Microstructural orientation mapping with a neutron beam
We propose to develop the means to measure the orientations, phases and strains of individual crystal grains within a polycrystal using neutrons. Such measurements have... -
Relating plastic deformation to angle dependent IGS for multiple hkl peaks
For some engineering purposes like welding or SCC where IGS (Inter Granular Stresses) increase susceptibility to cracking, some indicator of the level of plastic deformation... -
Stress evaluation of RAFM weld for fusion reactor
Reduced Activation Ferritic-Martensitic steels (RAFMs) are the primary candidate structural material for the FDS series LiPb blankets for fusion reactors, in particular the Dual...
