FE-BASED METALLIC GLASS ALLOYS WITH EXCELLENT GLASS FORMING ABILITY AND HARDNESS

摘要

According to the present invention, provided is a high hardness metal-based glass material with excellent amorphous forming ability having high hardness of 66 HRC or more by a casting process without heat treatment and a surface hardening process. Provided is a high hardness metal-based glass material comprising: in wt%, 1.0-2.5% of Nb, 1.8-2.5% of B, 0.3-0.6% of P, 1.0-2.5% of Hf, 4-5% of Ni, 1.5-2.5% of Mo, 1.0-2.0% of Mn, 0.8-1.0% of Si, and residues comprising unavoidable impurities and Fe.
