During continuous heating of a cold rolled low carbon (LC) steel a dilatometric anomaly has been detected previous to the well known ferrite-to-austenite transformation. This anomaly is due to the texture change and/or the dislocation annihilation that accompany the recrystallization process.

The recrystallization textures of a cold-rolled Al-Mn-Fe-Si model alloy with three different microchemistry states after non-isothermal annealing were studied. The microstructure and texture evolution have been characterized by EBSD. It is clearly demonstrated that the actual microchemistry state as determined by the homogenization procedure strongly influence the recrystallized grain size and ...

the evolution of texture was discussed during the formation of ultra-fine and nano grains in a magnesium alloy severely deformed through accumulative back extrusion (abe). the microstructure and texture obtained after applying multiple deformation passes at temperatures of 100 and 250°c were characterized. the results showed that after single abe pass at 100°c an ultrafine/nano grained microstr...

High energetic ions can lead to the formation of long columnar defects along the ion trajectories, so called “ion tracks”. In amorphous metals, overlapping tracks produce macroscopic anisotropic growth phenomena [1]. Characterization and imaging of single ion tracks in these materials is challenging and has been successful only in a few cases using chemical etching [2], scanning probe [3] and t...

Grain oriented silicon steel (GO) is mainly used as the core material in transformers, and it is the only product manufactured in the steel industry that applies the secondary recrystallization phenomenon. Its magnetic properties are closely related to the secondary recrystallization texture, i.e., the sharpness of 110 (001), Goss texture 1 . This sharp texture develops due to a discontinuous o...

The subgrain structure of hot rolled aluminum alloy AA 5005 has been characterized on as-received samples using Electron Backscatter Diffraction (EBSD). Based on the OIM scans of RD-ND and TD-ND, 3 dimensional microstructures of subgrains are built up using the 3D Microstructure Builder, which is a method for developing statistically representative digital representations of microstructures. Fo...

Steinernema feltiae is a moderately freezing tolerant nematode, that can withstand intracellular ice formation. We investigated recrystallization inhibition, thermal hysteresis and ice nucleation activities in the infective juveniles of S. feltiae. Both the splat cooling assay and optical recrystallometry indicate the presence of ice active substances that inhibit recrystallization in the nemat...

Total scattering pair distribution function (TSPDF) analysis of synchrotron X-ray diffraction data has been used to study the structural characteristics of amorphous lactose and its subsequent recrystallization on aging. This shows that the recrystallization kinetics vary substantially between spray dried, lyophilized, and melt quenched samples aged at 40 °C/75% relative humidity (RH), although...
