Microstructural Effects on the Surface of Materials in Magnetic Fields

详细

Changes in metallic and nonmetallic materials under the influence of a pulsed magnetic field are studied, using the method of target metallography. It is shown that the structural changes are at the minimum detectable level of the microscopic method with peak gains. It is established that local variation in structure and degradation in the sharpness of separate surface areas of the samples independent of errors in focusing is a general structure change in the action of a magnetic field. The stresses of the third kind are considered to be possible reasons for the change in structure.
