Anomalous thermal expansion in the deep super-cooled liquid region of a ZrCuAlAg bulk metallic glass

Anomalous thermal expansion in the deep super-cooled liquid region of a ZrCuAlAg bulk metallic glass

Bulk metallic glasses (BMGs), like other glasses, soften in the super-cooled liquid region (SCLR). Here in this work, surprisingly, a large expansion is reported occurring in the deep SCLR of a Zr47Cu37Al8Ag8 BMG. Nano-crystals (NCs) are found precipitated during the anomalous expansion of Zr47Cu37A...
