The　effects　of　partial　substitution　of　Ni　by　Pd　in　the　high-Zr-based　Zr65Al10Ni25-xPdx　(at.%,　x　=　0,　5　and　10)　alloys　on　their　glass-forming　ability　(GFA),　crystallization　kinetics　and　mechanical　property　were　investigated.　The　critical　diameter　for　glass　formation　is　increased　from　3　mm　for　Zr65Al10Ni25　alloy　to　5　mm　for　Zr65Al10Ni15Pd10.　An　icosahedral　quasicrystal　phase　precipitates　in　the　amorphous　matrix　in　the　first　crystallization　step　of　Zr-Al-Ni-Pd　BMGs,　implying　that　strong　icosahedral　short/medium-range　order　(IS/MRO)　may　exist　in　the　Pd-containing　alloys.　In　additional,　Pd-bearing　Zr-based　BMGs　present　a　lower　Avrami　exponent　n　indicating　the　higher　stabilization　of　the　supercooled　liquid.　Moreover,　the　Zr-Al-Ni-Pd　BMGs　exhibit　larger　compressive　plasticity,　higher　notch　toughness　and　Poisson＇s　ratio　than　those　of　Zr65Al10Ni25　alloy,　which　can　be　correlated　with　the　existence　of　strong　IS/MRO　clusters　in　amorphous　phase.　(C)　2016　Elsevier　B.V.　All　rights　reserved.
