Description:
The metastable nature of metallic glasses (MGs) limits their applications. We report the formation of a stable Pd 40.16 Ni 9.64 Cu 30.12 P 20.08 MG with bulk size under high pressure at room temperature. The stable MG shows remarkably enhanced thermal and kinetic stability with substantially increased glass transition temperature T g , crystallization temperature T x , density and mechanical properties. The unique stability can be further reinforced by higher pressure and maintained even above T g . This result can advance the glass design and the understanding of the fundamental issues in MGs.
