Embodiment 1
[0025] In the embodiment of the present invention, an alloy for precision machining lathe tool is composed of the following raw materials according to mass percentage: Mo12%, Nb8.6%, Zr10%, Hf5.6%, Ta2.8%, Si0.1% , Fe0.9%, the balance is Ti.
[0026] When preparing, include the following steps:
[0027] 1) Batching: batching is carried out according to the raw material composition and mass percentage ratio of the alloy used for precision machining lathe turning tools;
[0028] 2) Melting: Put the raw materials into a muffle furnace for melting, and control the temperature at 1250°C for 3 hours to obtain a molten alloy;
[0029] 3) Atomization: use argon as the injection medium to crush the molten alloy, and solidify into alloy powder in the cooling medium;
[0030] 4) Pressing: use ultra-high hydraulic tube expander to press the alloy powder, and the pressure parameter is 150MPa;
[0031] 5) Sintering: add a binder into the pressed alloy, put it into a muffle furnace for si...
