Preparing Fe–Ga sheets with excellent magnetostrictive coefficients by rolling and annealing methods can greatly promote the development of high-efficiency devices. 0.3 mm thick thin sheet was produced one-stage large-reduction cold method without intermediate annealing. Trace V Nb elements addition improves formability precipitating a large number (Nb,V)C particles. The evolution precipitation...

A 2D cellular automaton model developed for the simulation of grain growth in hexagonal metals is presented here. It allows the direct use of experimental measurement as input data. Texture evolution of a titanium alloy and a zirconium alloy are simulated on the basis of simple hypothesis and compared with experimental evolution as well as the results from a 3D Monte Carlo model. Results from b...

We present the results of a series of simulations of the growth of polycrystalline, faceted films in three spatial dimensions. The simulations are based upon the assumptions of the well known van der Drift model in which the growth rate of each surface is fixed only by its crystallographic orientation. The simulation method is based upon the level-set formalism and the only input are the relati...

The effect of additions of antimony (0.05% Sb) to silicon steel on the improvement of the electrical properties of non-oriented steel sheet was investigated. Measurements of surface segregation of Sb were performed under UHV conditions in the temperature range from 450 to 900 OC, using AES and TDS. Maximum equilibrium surface segregation of antimony was determined at 700 OC. At higher temperatu...

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...

As the available length ranges expand, graphene begins to show its anticipated polycrystallinity. Its texture, revealed with modern comprehensive microscopy in recent work by Kim et al. , includes coherent domains/grains oriented randomly yet with an intriguing degree of regularity. The domains are stitched together by pentagons and heptagons aligned into the grain boundaries. The challenge is ...

Silicon steel is a widely used soft magnetic material that requires different texture components for applications, typically classified as grain-oriented or non-oriented. However, the methods of fabricating such types silicon via laser-powder bed fusion (LPBF) have not been fully investigated. In this study, near and non-oriented Fe-3.5 wt.%Si fabricated using LPBF by controlling processing par...
