FE-BASED SOFT MAGNETIC GLASSY ALLOY MATERIAL

摘要

The invention is related to an Fe based alloy material, suitable for producing a soft magnetic glassy alloy product, a product produced thereof and a method for producing such a product. The product can be a master alloy product obtained after a first melting step starting from suitably selected starting materials, or it can be a final soft magnetic glassy alloy product obtained after a further step of melting the master alloy. The alloy material of the invention comprises : ⋅ C between 1.4wt% and 2.2wt% ⋅ Si between 0.9wt% and 1.35wt% ⋅ B between 0.43wt% and 0.65wt% ⋅ P between 5wt% and 7.5wt% ⋅ Mo between 0.9wt% and 9.2wt% ⋅ Mn between 0.05wt% and 0.6wt%, ⋅ O up to 0.3wt%, ⋅Al up to 0.1wt%, ⋅ S up to 0.05wt%, ⋅ Ti up to 0.45wt%, ⋅ Cr up to 0.3wt%, ⋅ Cu up to 0,25wt% or Cu between 0.25wt% and 0.8wt%, the balance being Fe and incidental impurities. A Fe-based soft magnetic glassy product according to the invention can be produced starting from non-pure starting materials.
