Abstract

A novel micro multi-physic fields coupling method(Micro-FAST) was developed for the fabrication of micro gears with 316 L stainless steel powders and pure copper powders. The effect of electric current magnitude on the particle deformation in sintering process of316 L stainless steel and pure copper systems was studied. It is shown that the calefactive period plays a key role for densification of powder system with the coupling of electric field, force field and temperature field. A notable feature of the densification process is plastic deformation of particles due to electroplastic effect. With the increasing of electric current, the deformation amount of particles is bigger which results in the increase of axial reduction, consequently improving the densification of samples.
