The metastable nature of metallic glasses (MGs) limits their applications. We report the formation of a stable Pd40.16Ni9.64Cu30.12P20.08 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 Tg, crystallization temperature Tx, density and mechanical properties. The unique stability can be further reinforced by higher pressure and maintained even above Tg. This result can advance the glass design and the understanding of the fundamental issues in MGs.
