【 摘 要 】

This study presents a series of new Mg-Ag-Y and Mg-Ag-Y-Cu bulk metallic glasses (BMGs) designed to obtain Mg-rich ductile glasses. Compressive ductility is observed in the selected alloys tested, involving compressive plastic strains of about 0.6% for the ternary BMGs obtained. Minor amounts of Cu generate a general increase in plastic strain up to about 0.8%. We report on the alloy design methodology, critical casting size, thermophysical properties and compression test data of these new alloys. (C) 2020 The Authors. Published by Elsevier B.V.
