Mechanical properties and crystallographic texture of non-oriented electrical steel processed by repetitive bending under tension

چکیده
Improving the magnetic properties of non-oriented electrical steel (NOES) through optimization crystallographic texture has been an on-going research activity for decades. However, using traditional rolling and annealing procedures, obtained final textures were usually very similar, i.e., exhibiting {111} (γ) <110> (α) fibres, which not desired {001} (θ-fibre) optimal quality. In current work, a 1.8 wt% Si NOES was processed new sheet metal deformation method, repetitive bending under tension (R-BUT), also known as continuous (C-BUT), to modify steel. The hot-rolled annealed plates repeatedly bent unbent when they pulled tension. deformed then heat treated at different temperatures various times. Neutron diffraction electron backscatter (EBSD) characterisation macro- micro-textures proved that R-BUT process significantly reduced undesired while promoting texture. cube texture, rarely formed after conventional annealing, seen in samples annealing. It shown that, shear plastic (induced by R-BUT) played significant role textures. addition, results indicated could be beyond its common formability limit, may provide method address poor workability challenge high silicon steels.

متن کاملMechanical Behavior of BFRP-Steel Composite Plate under Axial Tension
Combining the advantages of basalt fiber-reinforced polymer (BFRP) material and steel material, a novel BFRP-steel composite plate (BSP) is proposed, where a steel plate is sandwiched between two outer BFRP laminates. The main purpose of this research is to investigate the mechanical behavior of the proposed BSP under uniaxial tension and cyclic tension. Four groups of BSP specimens with four d...

In the present work, a high power Nd:YAG laser has been employed to weld AISI 430 ferritic stainless steel thin sheets. Optical microscopy was used to study the microstructural evolutions during laser welding. Tensile test and microhardness measurement were employed in order to investigate the mechanical behaviors of welds. Also, vibrational sample magnetometry was used for characterizing magne...
