Prediction of glass forming ability and glass forming range for electrodeposited binary Co-W alloys

This paper reports on the transition of crystalline to amorphous structure with increasing W content in electrodeposited binary Co-W alloys. The glass forming ability of the electrodeposited Co-based alloys, including Co-W alloy, is analyzed using deep eutectic criteria based on reduced liquidus temperature and relative composition ratio. MD simulations based on solid solution models indicated glass forming ability above 20 at. % W for Co-rich Co-W alloys, which is in good agreement with the experimental observations.
