Abstract

The origin of Zr₆₅Al_7.5Ni₁₀Cu _12.5Pd₅ and Zr₆₅Al_7.5Ni ₁₀Cu_12.5Nb₅ glassy alloys exhibiting a remarkable plastic strain of about 6% and over 10%, respectively, under compressive deformation is compared. Observation by transmission electron microscopic (TEM) indicates that the deformation-induced structural transformation from monolithic glassy phase is responsible for the large plasticity. The degree of structural change, however, is different between both alloys: the fcc-Zr₂Ni crystals emerged within glassy phase for the former, while only ordered clusters were observed for the latter. The difference is suggested to correlate to the slower grain-growth of the primary crystallization phase in the Zr₆₅Al_7.5Ni ₁₀Cu_12.5Nb₅ compared to those in the Zr ₆₅Al_7.5Ni₁₀Cu_12.5Pd₅ alloy.
