Strain-induced martensitic transformations in tailored microstructures by L-PBF: In situ characterization via advanced neutron imaging

Journal of Materials Research and Technology
The possibility of controlling the microstructure in laser powder bed fusion (L-PBF) by locally changing the processing parameters, opens the possibility of building complex structures with tailored microstructures, leading to the development of smart ...

High-resolution neutron depolarization microscopy of the ferromagnetic transitions in Ni$_3$Al and HgCr$_2$Se$_4$ under pressure

, 2018
We performed neutron imaging of ferromagnetic transitions in Ni$_3$Al and HgCr$_2$Se$_4$ crystals. These neutron depolarization measurements revealed bulk magnetic inhomogeneities in the ferromagnetic transition temperature with spatial resolution of ...
