Wear behavior of Fe-based bulk metallic glass composites

Composite samples comprising Fe-based metallic glass particles and the crystalline Ni matrix were produced. Wear behavior was investigated by a pin-on-disc type tester using hardened steel as the counter material. It was concluded that the wear mechanism depended on the volume fraction of crystalline nickel in the composites. The transition from the brittle fracture to the adhesive wear was observed by increasing the volume fraction of ductile Ni in the composites. (C) 2010 Elsevier B.V. All rights reserved.
