Embodiment 1
[0027] An induced Al 84 Ni 10 Gd 6 The method for phase separation of amorphous alloy includes the following steps:
[0028] (1) Preparation of the corrosive solution: the corrosive solution was prepared according to the volume fraction ratio of 27vol.% nitric acid and 73vol.% methanol, and placed in a beaker for later use.
[0029] (2) The Al prepared by the single roll spinning method 84 Ni 10 Gd 6 Amorphous strip samples were placed in a beaker containing a corrosive solution, and placed at room temperature for 120 hours. When placed, the beaker needs to be sealed with plastic wrap to reduce the volatilization of the solution.
[0030] (3) Take out the sample after the set time and place it in a container filled with deionized water for ultrasonic vibration cleaning to obtain a phase-separated amorphous sample. Where the Al 84 Ni 10 Gd 6 The width of the amorphous alloy strip is 3mm and the thickness is 30μm.
[0031] (4) Perform XRD test on the obtained amorphous sample ( figure 1...
Embodiment 2
[0034] (1) Preparation of corrosive liquid: the corrosive medium is prepared according to the volume fraction ratio of 27vol.% nitric acid and 73vol.% methanol.
[0035] (2) Pour the corrosive medium into the double-jet electrolytic thinner, and then pour the Al 84 Ni 10 Gd 6 The amorphous strip is placed in a double-jet electrolytic thinner for thinning, and thinning is performed at -20°C for 3 minutes. Where the Al 84 Ni 10 Gd 6 The width of the amorphous alloy strip is 3mm and the thickness is 30μm.
[0036] (3) Take out the sample after the set time and place it in a container filled with deionized water for ultrasonic vibration cleaning to obtain a phase-separated amorphous sample.
[0037] (4) Observation of the prepared sample by transmission electron microscope, it can be found that figure 2 The phase separation can be reflected in the small dot-like structure between light and dark. The measured pore size of the sample is in the range of 1 nanometer to 5 microns, and the vo...
Embodiment 3
[0040] An induced Al 84 Ni 10 Gd 6 The method for phase separation of amorphous alloy includes the following steps:
[0041] (1) Preparation of corrosive solution: The corrosive solution was prepared according to the volume fraction ratio of 20vol.% nitric acid and 80vol.% methanol, and placed in a beaker for later use.
[0042] (2) The Al prepared by the single roll spinning method 84 Ni 10 Gd 6 Amorphous strip samples were placed in a beaker containing a corrosive solution and placed at room temperature for 100 hours. The beaker should be sealed with plastic wrap to reduce the volatilization of the solution. Where the Al 84 Ni 10 Gd 6 The thickness of the amorphous alloy strip is 20-40 μm and the width is 2-4mm.
[0043] (3) Take out the sample after the set time and place it in a container filled with deionized water for ultrasonic vibration cleaning to obtain a phase-separated amorphous sample.
[0044] (4) Performing XRD test on the obtained amorphous sample, it can be found that...
