采用平行板流变仪和三点梁弯曲法，在从平衡过冷液态到玻璃转变区域的较宽温度范围内测量了Pd43Ni10Cu27P20大块金属玻璃形成液体的平衡粘度。基于所测粘度数据，定量确定了该液体的脆性。尽管Pd43Ni10Cu27P20合金展现出了迄今为止所报道的最佳玻璃形成能力，但与其他大块玻璃形成液体（如Vit 1和Vit 4）相比，其相对较脆。（C）2004美国物理学会。
The equilibrium viscosity of the Pd43Ni10Cu27P20 bulk metallic glass-forming liquid was measured over a wide temperature range from the equilibrium supercooled liquid state to the glass transition region using parallel-plate rheometry and three-point beam bending. Based on the measured viscosity data, the fragility of this liquid was quantitatively determined. The Pd43Ni10Cu27P20 alloy, despite exhibiting the best glass-forming ability reported thus far, is relatively fragile compared with other bulk glass-forming liquids, such as Vit 1 and Vit 4.
