Crystal Grain Shape Aspect of Grain Oriented Steel by Three Dimensional Polycrystalline Magnetic Field Analysis

Magnetite grain shape fabric and distribution anisotropy vs rock magnetic fabric: a three-dimensional case study

ÐShape fabric and distribution anisotropy of magnetite grains in a highly ferromagnetic (s.l.) syenite are determined for three mutually perpendicular planes on about 600 magnetite grains. The grains are lenticular with an average aspect ratio of about 2.0. Their preferred orientation, determined by the inertia tensor method, is consistent with the principal directions of the magnetic susceptib...

Secondary recrystallization characteristics of 3%Si grain-oriented electrical steel

A secondary recrystallization Lab study focusing on the secondary recrystallization temperature and magnetic properties was carried out on cold rolling industrial samples of 3%Si grain-oriented electrical steel produced by low slab reheating temperature technology. The results showed a secondary recrystallization temperature, determined by the observed grain size change, of 1080 C with annealin...

Residual Stress Distribution in Grain-oriented Silicon Steel

We investigated the residual stress distribution in a grain of laser-irradiated and gearrolled grain-oriented Fe-3%Si silicon steels by X-ray stress measurement method in order to clarify the effect of residual stresses on magnetic domain refining. Dotted cavity lines were formed by Nd:YAG laser with a power density of 3.3 mJ/pulse for the laserirradiated sample. By using a newly developed X-ra...

Three-dimensional structure of a single colloidal crystal grain studied by coherent x-ray diffraction.

A coherent x-ray diffraction experiment was performed on an isolated colloidal crystal grain at the coherence beamline P10 at PETRA III. Using azimuthal rotation scans the three-dimensional (3D) scattered intensity from the sample in the far-field was measured. It includes several Bragg peaks as well as the coherent interference around these peaks. The analysis of the scattered intensity reveal...
