Neutron diffraction was employed to measure internal residual stresses at various locations along stainless steel (SS) 17-4 PH specimens additively manufactured via laser-powder bed fusion (L-PBF). Of these specimens, two were rods (diameter=8 mm, length=80 mm) built vertically upward and one a parallelepiped (8×80×9 mm3) built with its longest edge parallel to ground. One rod and the parallele...
in 1960’s, but showed little development, as the thermal and epithermal neutron sources were not economical. Nuclear reactors, and recently cyclotrons are being used as neutron sources, thus enabling its widespread utilization (1). Gamma rays are utilized for the irradiation of tumor tissues, and fractional doses up to 50-60 Gray required for tumor ablation in conventional radiation therapy. Su...
Neutron diffraction has proven to be an indispensable and highly significant tool since its development 60 years ago. The neutron has unique properties that yield distinct information unavailable otherwise. Chief among these properties is the relative uniformity of the neutron scattering power of atoms across the periodic table, allowing the accurate structure determination of materials compose...
The specific heat of Ce3Co4Sn13 exhibits a crossover from heavy Fermion behavior with antiferromagnetic correlations at low field to single impurity Kondo behavior above 2T. We have performed neutron diffraction measurements in magnetic fields up to 6T on single crystal samples. The (0 0 1) position shows a dramatic increase in intensity in field which appears to arise from static polarization ...
