Abstract

The invention relates to a method for reducing the embrittlement degree of an amorphous strip. The method comprises the steps of configuring a master alloy, and adding a certain amount of microelement Zn into an iron-base alloy to prepare an alloy of which the chemical component expression is (Fe[100-x]Znx)aSibBc based on atom number percent, wherein the atom percentage contents of a, b, c and x are as follows: a is more than or equal to 78 and less than or equal to 82, b is more than or equal to 8.5 and less than or equal to 10, c is more than or equal to 10.5 and less than or equal to 12, and x is more than or equal to 8.5 and less than or equal to 10; smelting the master alloy in a smelting furnace, and preparing an amorphous strip by adopting a single-roller rapid solidification production process; performing magnetic-field heat treatment on the amorphous strip at a certain temperature. According to the method, by starting with component design and a smelting link during strip preparation, the component range of a main element alloy which ensures that the strip keeps excellent magnetic performance is determined at first, and then an appropriate amount of microelements are added on the basis of the component range, so that the embrittlement degree of the prepared amorphous strip is significantly reduced after the magnetic-field heat treatment.

Description

technical field [0001] The invention relates to the field of amorphous strips, in particular to a method for reducing the brittleness of amorphous strips. Background technique [0002] Amorphous alloys have many unique properties, such as excellent magnetic properties, corrosion resistance, wear resistance, high strength, hardness and toughness, high electrical resistivity and electromechanical coupling, and are known as a branch of metallurgical materials science. revolution. Amorphous alloys are solidified by ultra-extreme cooling. When the alloy is solidified, the atoms do not have time to arrange and crystallize in an orderly manner. The obtained solid alloy has a long-range disordered structure, and there are no grains and grain boundaries of the crystalline alloy. Due to its excellent performance and simple process, it has become the focus of research and development in the field of material science at home and abroad since the 1980s. In the past thousands of years, ...
