By numerical and experimental methods, heat alternating magnetic treatment of diamond agglomerations were researched, the microstructure and mechanical properties before and after treatment were also analysed comparatively. The numerical analysis shows: the alternating magnetic field stress is bound to make solid-state microstructure change, this intensified magnetic shock can broke dendrites and tangles organization within the organization and enables organization uniform, dense. The experiments indicate: After heat alternating magnetic treatment, the HRB hardness of test pieces matrix is improved 4.34, impact toughness enhanced more than 25%, matrix organization became uniformity and density. Results revealed that alternating magnetic treatment can be an effective method for improving the performance of the diamond agglomeration. |
