| Abstract: | The dissertation is focused on the influence of pulse electric field on the solidification microstructures and shape memory effect of FeMnSiCr alloys. By imposing pulse electric field in the solidification process of the FeMnSiCr, it is found that crystal grain of solidification microstructures obtained refinement and the columnar crystal was obtained which is inclined to shape memory recovery. The shape memory effect was obviously en- hanced. When the parameters of pulse electric discharging are 250V and 3Hz, the shape memory effect of FeMnSiCr alloy in the cool area is best. |
