Wear behavior of bulk Zr₄₁Ti₁₄Cu_12.5Ni₁₀Be_22.5 metallic glasses

The wear behavior of bulk Zr₄₁Ti₁₄Cu_12.5Ni₁₀Be_22.5 metallic glasses has been studiedusing sliding wear tests and scanning electron microscopy in both as-prepared and annealed samples. It was found that the wear resistance of differently processed samples increases in the following order: crystallized state; as-prepared state; relaxed state. The thermal stability of worn samples was also investigated by means of differential scanning calorimetry. Under the experiment conditions, no sliding wear-induced crystallization is observed in either as-prepared or relaxed samples indicating good thermal stability of the bulk metallic glasses.
