Pulsed Magnetic Treatment of Cobalt for Enhanced Microstructures and Mechanical Properties

In this study, the effects of pulsed magnetic treatment (PMT) on microstructure and performance pure bulk cobalt (Co) were investigated to reveal underlying influencing mechanism field ferromagnetic materials. The hardness material could be increased by PMT, with a maximum increase 3.16% when 1T was adopted. imposition promoted transformation Co from face-centered cubic (FCC) phase hexagonal close-packed (HCP) phase, which obeys Shoji–Nishiyama orientation rule, decrease α-Co 8.60% an ε-Co 0.19%. PMT also caused multiplication defects formation low-angle grain boundaries within Co. effective way modify materials suit engineering applications.
