The invention discloses a metallic material acute plastic deformation extrusion die and a using method of the die. The die comprises an extrusion barrel, an extrusion stem, an extrusion stem die holder and an extrusion cushion block. Extrusion channels are arranged in the extrusion barrel. An extrusion sample is arranged in the extrusion channels. The extrusion channels include the vertical extrusion channel and the transverse extrusion channel. The upper end of the vertical extrusion channel communicates with the upper surface of the extrusion barrel. The lower end of the vertical extrusion channel communicates with one end of the transverse extrusion channel. The other end of the transverse extrusion channel communicates with the surface of the side wall of the extrusion barrel. The extrusion stem penetrates through the vertical extrusion channel. The upper end of the extrusion stem is fixedly connected with the extrusion stem die holder. The lower end of the extrusion stem makes contact with the extrusion
