Field‐Programmed Anisotropy in Magneto‐Piezoelectric Composites for Material‐Encoded Mechanoperception

Advanced Materials, EarlyView.
Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

Effects of magnetic field and post-weld heat treatment on microstructure and properties of laser welded joints of 22MnB5-TRIP590 steel

Materials Research Express
Laser welding without and with an auxiliary magnetic field (B = 30 mT) is performed on 22MnB5-TRIP590 steel. Subsequently, post-weld heat treatment, involving quenching at 800 °C followed by tempering at 200 °C, is carried out on the welded joints ...
