2, the method for smelting of ZrTiAlV alloy:
1. preparing diameter is 24 ~ 35mm, is highly cylinder 47Zr-45Ti-5Al-3V alloy or the 30Zr-62Ti-5Al-3V alloy of 25 ~ 40mm;
2. the cavity between the seaming chuck of above-mentioned electric discharge smelting apparatus and tubular die sleeve put into by alloy cylinder step 1. prepared;
3. above-mentioned electric discharge smelting apparatus entirety is put into discharge plasma sintering machine and carry out melting.By loading 3000 ~ 5000A pulse current, seaming chuck is descending to be made it contact with die sleeve to the pressure of tubular die sleeve 10 ~ 30MPa to seal, and by vacuum pumping in sintering machine, vacuum is 10
-3pa, prevents alloy oxidized.
4. pulse current is loaded on cylinder alloy by seaming chuck and tubular die sleeve, is incubated 20min after making alloy rapid temperature increases to 1800 DEG C;
5. last discharge sintering device powers down, cools naturally, after the cooling of this device, takes out electric discharge smelting apparatus, takes out the alloy after melting.
The present invention compared with prior art tool has the following advantages:
This electric discharge smelting apparatus structure is simple, and its seaming chuck is special shoulder type seaming chuck, pressure-loaded at the upper surface of tubular die sleeve, can reach the effect of sealing heat conduction, can not be subject to smelting temperature and material molten state limit when seaming chuck is stressed; And the lower part of seaming chuck does not directly contact with material sample, push-down head design is simultaneously integrated with tubular die sleeve, the material of molten condition can not be made to be flowed out by gap between seaming chuck and tubular die sleeve like this and pollute sintering machine environment when carrying out high melt to material sample because pressure is excessive.
