Embodiment 1-22
[0062] Using common industrial raw materials, the smelting component is Fe 83 C 1 m f Si b B c P d Alloys, Examples 1-22. M element is the impurity in the raw material when Fe, Si, B, P and C elements are added, regardless of the influence of its type and content f, only its influence on the performance of the alloy is considered as a whole.
[0063] The molten alloy is sprayed onto a 30m / s rotating copper roller through a nozzle of a certain shape to prepare an alloy strip with a width of about 1mm and a thickness of about 25μm. The strip is determined to be amorphous by XRD. The strips were used to test the magnetic properties of the samples after heat treatment and the toughness of the strips before and after heat treatment.
[0064] Obtain the thermodynamic parameters (comprising the Curie temperature T of the amorphous alloy) of the above-mentioned prepared amorphous alloy with differential scanning calorimetry c , initial crystallization temperature T x1 and liqu...

[0080] With common industrial raw materials, the smelting components are (Fe 83 Si 2.5 B 10.5 P 3 ) (100-x) / 99 C x Alloys, Examples 23-28. M element is the impurity in the raw material when Fe, Si, B, P and C elements are added, regardless of the influence of its type and content f, only its influence on the performance of the alloy is considered as a whole.
[0081] Use a nozzle of a certain shape to spray onto a 30m / s rotating copper roller to prepare an alloy strip with a width of about 1mm and a thickness of about 25μm. XRD is used to confirm that the strip is an amorphous structure. The magnetic properties of the samples after heat treatment and the toughness of the strips before and after heat treatment were tested with 25 μm thick amorphous ribbons.
