Examples
Embodiment 1
[0025] Preparation of TiZr-based amorphous composite material with O content of 6 at.%:
[0026] The first step: Weigh the pure metal raw material and CuO (purity greater than 99.9%) according to the atomic percentage of No. 1 in Table 1, wherein O is added in the form of CuO, Cu is added in the form of CuO and pure metal Cu, and the remaining elements are added in the form of pure metal , weighing accuracy is 0.001g;
[0027] The second step: smelting in a high-vacuum non-consumable electric arc furnace to obtain an 80g master alloy ingot;
[0028] Step 3: Take 25g of the master alloy and cast it into a copper mold to obtain a rod-shaped sample with a diameter of 8mm.
Embodiment 2
[0030] The difference between this example and Example 1 is that its O content is different, and the O content of the prepared composite material is 1 at.%; O is represented by ZrO 2 Form added, Zr as ZrO 2 And pure metal Zr form added.
[0031] The first step: take the pure metal raw material and ZrO according to the atomic percentage of No. 2 in Table 1 2 (purity greater than 99.9%), weighing accuracy is 0.001g;
[0032] Second step: same as embodiment 1;
[0033] The third step: same as embodiment 1.
Embodiment 3
[0035] The difference between this example and Example 1 is that its O content is different, and the O content of the prepared composite material is 5 at.%; O is represented by TiO 2 Form added, Ti as TiO 2 And pure metal Ti added.
[0036] The first step: Weigh the pure metal raw material and TiO according to the atomic percentage of No. 3 in Table 1 2 (purity greater than 99.9%), weighing accuracy is 0.001g;
[0037] Second step: same as embodiment 1;
[0038] The third step: same as embodiment 1.
