Abstract The heated test pieces of diamond segments were treated by alternating magnetic field, the influences of magnetic treatment on microstructure densification of diamond segments were studied through metallurgical structure analysis. The experiment results indicate: the densification of diamond segments was further improved after magnetized. The alternating magnetic force distributions in the diamond segments were calculated by numerical simulation according to the coupled field theory. In alternating magnetic field, a prodigious swirl current field appeared in the component. The magnetic vibrating due to alternating magnetic force was very obvious, which was in favor of microcosmic structure compacter. The numerical analysis results provided intuitionistic evidences for that the alternating magnetic treatment can act as one kind of effective technique to improve the microstructure densification of diamond segments.
