Embodiment 1
[0020] The aging treatment of CuNiMnFe alloy under the action of compressive stress improves the plasticity and toughness, and the cast CuNiMnFe alloy is processed into a cuboid with a size of 16mm×16mm×100mm;
[0021] Place the processed CuNiMnFe alloy in the SX-10-12 box-type resistance furnace, set the solid solution temperature to 520°C, hold the temperature for 60 minutes, water quench to room temperature, and polish the surface with sandpaper for later use;
[0022] The CuNiMnFe alloy after solid solution treatment was placed in the hot-press mold in the SLQ-16B atmosphere-protected hot-press sintering furnace. In order to prevent the alloy from being oxidized, H 2 , heated for 20min until the aging temperature is 430°C, and held for 1440min. During the heat preservation process, the hot pressing mold was pressurized by 5MPa. After the CuNiMnFe alloy aging time reached the corresponding set value, it was cooled with the furnace. The cooling process was at N 2 It is compl...
