Amorphous alloy and process for producing products made thereof

A process for producing an amorphous Fe-based bulk metallic glass product, formed of an alloy having a chemical formula of

• Fe100-a-b-c-d-x-y MaNbbSicBdlxJy wherein:
• M is Co and/or Ni,
• I is one or more elements of the group consisting of Al, Cr, Cu, Mn, C and P,
• J is one or more elements of the group consisting of Ti, S, N and O
• and wherein a, b, c, d, x and y are satisfying the following conditions:
• 0 wt. %≦a≦46.1 wt. %, 5.4 wt. %≦b≦12.4 wt. %, 2.2 wt. %≦c≦4.4 wt. %, 2 wt. %≦d≦6 wt. %, x<2 wt. % and y<0.2 wt. %, the process comprising the steps of:
• Providing starting materials, comprising Fe-containing alloys,
• Melting said starting materials at a temperature above the melting temperature of said materials,
• Keeping the materials in a molten state,
• Pouring the molten materials into a mould,
• Cooling the molten material, to obtain a master alloy,
• Introducing the master alloy in a melting device,
• Heating up the master alloy to a temperature above its melting temperature to obtain a molten material,
• Pouring the molten material into a mould,
• Cooling the molten material, to obtain the product.
