Abstract
PURPOSE: To provide a high permeability amorphous alloy with high hardness and superior mechanical characteristics, obtd. by making an alloy contg. Fe+Co and B or B+Si in a specific ratio amorphous.
CONSTITUTION: The amorphous alloy is obtd. by making an alloy of formula (T1-a.Nba)1-b.Xb amorphous by quenching, etc. In the formula, T is Fe, Co or Fe+Co, the Fe content is 3W8 atomic% of the total amt. of Fe, Co and Nb, X is B or B+Si, the Si content is below 25 atomic%, a is 0.005W0.10 and b is 0.15W 0.35. The alloy has superior hardness, mechanical characteristics and permeability, and hence it is suitable for use at a magnetic head material for magnetic recording.
