A new alloy, known as Cu50Zr50 amorphous alloy, has shown exceptional spall strength that exceeds the E/10 limit at strain rates greater than 107 s−1. Amorphous alloys are a class of materials that lack a long-range crystalline structure, making them more resistant to deformation and damage. This property is what makes the Cu50Zr50 amorphous alloy so strong and tough.
Exceptional Spall Strength and Strain Rate Performance
The Cu50Zr50 amorphous alloy has demonstrated exceptional spall strength, exceeding the E/10 limit at strain rates greater than 107 s−1. This is a remarkable property, as it suggests that the alloy is highly resistant to damage and deformation even under extreme loading conditions.
Amorphous Structure and Resistance to Deformation
The unique amorphous structure of the Cu50Zr50 alloy is what contributes to its exceptional strength and toughness. Unlike crystalline materials, amorphous alloys lack a long-range ordered structure, which makes them more resistant to deformation and damage. This property is what sets the Cu50Zr50 amorphous alloy apart and makes it a promising candidate for applications where high strength and toughness are required.
