[0029] The preparation method of the hydrogen-containing titanium-based bulk amorphous alloy, the specific steps of the preparation method are as follows:
[0030] Step 1: Prepare master alloy ingot by electric arc melting: Ti, Zr, Cu, Ni, Al with a purity of not less than 99.9%, raw materials according to (Ti a Zr b Cu c Ni d Al e )H x The atomic ratio is put into the water-cooled copper crucible in the vacuum melting chamber, and the melting chamber is evacuated to a vacuum degree of 6×10 -3 Below Pa; then pass in different proportions of hydrogen-argon mixed gas, the total pressure of the experiment is 50KPa; the raw materials are repeatedly smelted several times under the hydrogen-argon atmosphere, and the number of smelting is generally 3-5 times. Smelt for 1-2 minutes each time to obtain uniform alloy button ingots;
[0031] Step 2: Obtain amorphous alloy by copper mold suction casting method: use copper mold suction casting method to suck and cast the alloy button...
Embodiment 1
[0035] This example adopts the method of suction casting of copper mold to prepare titanium-based bulk amorphous alloy (Ti) under pure argon atmosphere. 50 Zr 10 Cu 40 )H 0.002 .
[0036] Step 1: Press Ti, Zr and Cu raw materials with a purity of 99.9% into Ti 50 Zr 10 Cu 40 The atomic ratio is put into the water-cooled copper crucible in the vacuum melting chamber, and the melting chamber is evacuated to a vacuum degree of 6×10-3 Below Pa; then pass high-purity argon gas, the total pressure of the experiment is 50KPa; under the pure argon atmosphere, the raw materials are repeatedly smelted three times, each time for about one minute, so as to obtain a uniform alloy button ingot.
[0037] Step 2: Inhale the alloy button ingot prepared in step 1 into a copper mold by a suction casting method to prepare a bulk amorphous alloy. Specifically, under the condition of sub-rapid cooling, the smelted alloy melt is absorbed and cast into the copper mold cavity by using the pressu...
Embodiment 2
[0041] The titanium base bulk amorphous alloy (Ti 50 Zr 10 Cu 40 )H 0.017 .
[0042] Step 1: Press Ti, Zr and Cu raw materials with a purity of 99.9% into Ti 50 Zr 10 Cu 40 The atomic ratio is put into the water-cooled copper crucible in the vacuum melting chamber, and the melting chamber is evacuated to a vacuum degree of 6×10 -3 Below Pa; then feed the mixed gas of hydrogen and argon containing 5% hydrogen, the total pressure of the experiment is 50KPa; under the mixed atmosphere of hydrogen and argon, the raw materials are repeatedly smelted three times, each time for one minute, so as to obtain a uniform alloy button ingot.
[0043] Step 2: Inhale the alloy button ingot prepared in step 1 into a copper mold by a suction casting method to prepare a bulk amorphous alloy.
[0044] The structure of the obtained samples was analyzed by X-ray diffraction method, figure 2 is the XRD pattern of the sample.
