Enhanced kinetic stability of a bulk metallic glass by high pressure

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 glas...

Description
Summary: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 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.
