Embodiment 1
[0031] With finished Fe 76 PCSi 6 B 16 Take the amorphous alloy thin strip as an example, the number in the chemical formula is at%, and the specific operation steps are as follows:
[0032] Step S1, establish the relationship between alloy melt viscosity and alloy composition: (1) Prepare a series of different non-metal element components Fe by changing the ratio of non-metal elements Si and B with different coordination numbers in the iron-based amorphous alloy 76 PCSi 22-X B X alloy melts, where the value of X ranges from 11 to 16; then the viscosity of these alloy melts is measured at 1300°C with a high-temperature viscosity measuring instrument (product of GBX Company, model: Viscodrop 2000), and the viscosity of the alloy melts varies with The characteristics of the composition changes of different Si and B nonmetallic elements;
[0033] Step S2, establishing the relationship between the critical thickness of the amorphous alloy strip and the viscosity of the alloy ...
