Embodiment 1
[0016] This embodiment adopts suction casting method to prepare the Cu of diameter 6mm 45 Zr 46 al 7 Ti 2 Bulk amorphous alloys (amorphous alloys whose size reaches the order of millimeters are called bulk amorphous alloys).
[0017] Step 1: Put 99.95% pure Cu, 99.87% pure Zr, 99.5% pure Al and 99.98 pure Ti into Cu 45 Zr 46 al 7 Ti 2 The ratio is arc smelted in an argon atmosphere adsorbed by zirconium to obtain a uniformly mixed alloy ingot.
[0018] Step 2: Melt the ingot obtained in Step 1 on a water-cooled copper mold in an argon-protected melting furnace.
[0019] Step 3: inject the alloy liquid obtained in step 2 into a water-cooled copper mold with an inner diameter of 6 mm by using the pressure difference. A bulk amorphous alloy is produced.
[0020] Step 4: Characterize the bulk amorphous structure by X-ray diffraction method, and Fig. 1 is the X-ray diffraction diagram of the sample.
[0021] Step 5: Obtain the thermodynamic parameters of the bulk sample u...
