Abstract
The present disclosure discloses a method for preparing large-size rare earth magnesium alloy with high-performance ingots by short process severe plastic deformation. When in use, the pushing cylinder moves upward, and the back pressure plate is adjusted to the outlet of the extrusion deformation area. After the male mold stroke is completed, the recoverable discard block fills the extrusion deformation area, and the upsetting extrusion deformation is completed. Then, the pushing cylinder drives the back pressure plate to remove from the lower part of the lower mold cavity downward, and the recoverable discard block has been broken due to the high pressure. Then, the extruded blank and residual block powder are taken out from the lower part of the lower mold cavity, restored into a plate shape for the next use. The present disclosure can solve the tail shrinking phenomenon, save materials and increase the strengthening effect.
