Abstract

In this work, the peculiarities of the manufacturing of the details from powder materials with complicated shape by the method of magnetic pulse processing are presented. The special attention is given to the Fe-Cu powder materials which are used for complicated shape moulds manufacturing for thermoplastics casting. Magnetic pulse processing of materials (MIOM) include following operations, such as magnetic pulse pressing of powders and sintering with infiltration. The optimal values of the magnetic field intensity, discharge current and working voltage are determined. Post processing of the Fe-Cu details in the pulse electromagnetic field furthers the density rise на 7 % – 10 % and the additional changes of the detail shape.
