Change of brass structure under its exposure to pulsed magnetic field

Abstract

The structure change of the Cu-42% Zn alloy (brass) was investigated under its exposure to a pulsed magnetic field. Metallographic examinations have revealed that the alloy grains are refined with forming twins inside them. Compressive macrostresses are set up on the surface of the alloy samples under the action of a pulsed magnetic field. The alloy structure and properties are shown to change periodically depending on the value of discharge energy and the number of magnetic pulses.
