Copper Base Ductile Bulk Metallic Glass

Facility for melting and suction casting

Chances of abrupt failures will be minimal and hence these materials would be useful for structural applications requiring high strength and ductility.

• Using the indigenously developed suction casting assembly of Cu-based bulk metallic glass with good strength and comparatively high plastic strain / ductility
• This process produces materials exhibiting reasonable plastic strain without diminution of their strength at room temperature through minor addition, thereby overcoming the major drawback of BMG to a reasonable extent.
• Cu-based BMG of the present invention has excellent mechanical properties; such as high compressive strength (2200 Mpa), reasonable ductility (20 %), and hence can be considered potential materials for developing small machine components.
