An Experimental Setup for Studying the Deformation Dynamics of Metal Samples under Pulsed Magnetic Field

An experimental setup for studying the dynamics of deformation of a metal sample under the action of a magnetic-field pulse of a complex shape is presented. The slow part of a pulse has forward polarity (the amplitude is up to 15 T), while the fast part consists of a sequence of reverse-polarity pul...

Description
Summary:An experimental setup for studying the dynamics of deformation of a metal sample under the action of a magnetic-field pulse of a complex shape is presented. The slow part of a pulse has forward polarity (the amplitude is up to 15 T), while the fast part consists of a sequence of reverse-polarity pulses (the amplitudes are up to 4 T). This creates a pressure that causes attraction of a sample to an inductor. The device consists of four pulse current sources that operate simultaneously into one inductor. The generation of a pulsed magnetic field by inductors of two types is considered: a flat inductor (a double flat spiral) and a cylindrical inductor with a cutout concentrator of the magnetic field. The setup is equipped with a multipoint system for measuring the dynamics of the plate deformation during the exposure. The possibility of plastic deformations of copper, aluminum, and steel plates with thicknesses of up to 1 mm is shown.
