Title:
AMORPHOUS STRIP MASTER ALLOY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/143703
Kind Code:
A1
Abstract:
An amorphous strip master alloy and a preparation method therefor, relating to the field of amorphous materials. The preparation method comprises: providing an amorphous alloy and cementite Fe3C; and placing the amorphous alloy and the cementite Fe3C in a smelting furnace for smelting so as to obtain an amorphous strip master alloy. The elements constituting the amorphous alloy comprise Fe, Si, and B. The amorphous alloy and the cementite Fe3C are used as raw materials and smelted, and the cementite Fe3C can be added into the amorphous alloy to form the expected amorphous strip master alloy. The cementite has magnetism, and therefore, the magnetic induction intensity of the amorphous strip master alloy is significantly improved. When the amorphous strip master alloy is used for preparing the amorphous strip, the magnetic induction intensity of the amorphous strip can also be significantly improved.
