Embodiment 1
[0032] Ingredients: Weigh raw materials according to the composition and mass percentage of the above-mentioned corrosion-resistant metal shelves, including Tl: 5%, Be: 0.4%, C: 0.7%, Os: 0.8%, Pb: 2%, Sn: 3%, Ir : 0.6%, the balance is Fe and impurities, wherein the impurities include S<0.055%, O<0.015%.
[0033] Powder making: Put the raw material powder mixed in proportion into the jet mill, feed nitrogen, set the nitrogen pressure to 0.8MPa, and obtain alloy powder after continuous processing for 135 hours.
[0034] Compression molding: Fill the alloy powder into the mold of each part of the prefabricated shelf, fill it with nitrogen until the pressure in the mold reaches 3 atmospheres, and take out the blanks of each part after pressing for 4 hours.
[0035] Sintering: put the blank into the sintering furnace, first pre-sinter at 700°C for 1.5h, and carry out repressing treatment at the same time, then sinter the blank at 1100°C for 4h, then cool to room temperature, and f...
