[産業上の利用分野コ
この発明は磁気ヘッドなどに利用されるアモルファス磁
性合金に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an amorphous magnetic alloy used in magnetic heads and the like.
[従来の技術]
アモルファス(非晶質)金属は非晶化するため、例えば
溶融液体金属を急冷してつくられる。[Prior Art] Amorphous metals are made by rapidly cooling molten liquid metals because they become non-crystalline.
このようにしてつくられたアモルファス金属は規則的な

結晶状の金属とは異なった種々の特徴をもっており、こ
のため近年各分野から注目されるよう1こなった。Amorphous metals created in this way are non-crystalline and do not have a regular atomic arrangement, so they have various characteristics that are different from ordinary crystalline metals. I did one thing to get noticed.
例えば、鉄を主材としたアモルファス磁性合金は結晶磁
気異方性がないため保持力が小さくて、透磁率が高い。For example, an amorphous magnetic alloy mainly made of iron has low coercive force and high magnetic permeability because it has no crystal magnetic anisotropy.

透磁率の高い、かつ耐摩耗性のよい磁性材料が望まれて
いた。Due to its high hardness, it has good wear resistance, and since there are no crystal grains or grain boundaries, precision machining of gaps is possible, so its application to magnetic heads has attracted attention. However, when used in magnetic heads, it is still inferior to Permalloy 1 in terms of coercive force and permeability, and it is not as good as ferrite in terms of wear resistance, so the holding force is smaller.
A magnetic material with high magnetic permeability and good wear resistance has been desired.

ァス磁性合金を得ることができる。[Means and effects for solving the problems] The present invention is an amorphous magnetic alloy characterized by mixing an iron-based alloy material with a niobium-based substance to make it amorphous,
By melting and mixing a niobium-based substance into the alloy composition, the niobium-based substance acts on the alloy composition when it becomes amorphous, thereby obtaining an amorphous magnetic alloy with small retention, high magnetic permeability, and good wear resistance. Can be done.

得られた。An alloy material having a composition of 1 to 15% by weight of niobium Nb is mixed therein and melted at high temperature to form a liquid metal,
This liquid metal is sprayed from a nozzle onto a low-temperature roller that rotates at high speed, and is rapidly cooled and amorphized at a rate of 10" to 106°C/sec. The amorphous magnetic alloy thus created is mixed with niobium Nb. A magnetic material was obtained in which the coercive force and magnetic permeability were improved by about 10 degrees, and the hardness was increased and the wear resistance was improved by about 15 degrees compared to an amorphous magnetic alloy with the same weave.
