Machining chips and bulk discs of an amorphous Zr50Cu30Al10Ni10 alloy were processed by high-pressure torsion (HPT). It was confirmed that the machining chips can be consolidated using HPT at room temperature to disc-shaped samples with 10 mm diameter and 0.6 mm thickness having a relative density of 96.7%. The hardness for the consolidated chips was well comparable to those obtained using the bulk samples when the imposed strain is large. No crystallization was detected after HPT processing of chips and bulk samples. [doi: 10.2320/matertrans.MB200914]
