Zirconium-Cobalt-Nickel-Aluminum Glasses with High Glass Forming Ability and High Reflectivity

摘要

The disclosure is directed to Zr—Co—Ni—Al alloys that optionally comprise Ti and are capable of forming metallic glasses having a combination of high glass forming ability and high reflectivity. Compositional regions in the Zr—Co—Ni—Al and Zr—Ti—Co—Ni—Al alloys are disclosed where the metallic glass-forming alloys demonstrate a high glass forming ability while the metallic glasses formed from the alloys exhibit a high reflectivity. The metallic glass-forming alloys demonstrate a critical plate thickness of at least 2 mm, while the metallic glasses formed from the alloys demonstrate a CIELAB L* value of at least 78.
