The　glass　forming　ability,　mechanical　properties　and　corrosion　resistance　of　Ce69.5-xCu18Al11Nb1.5Yx(x=0,1,2,3)　bulk　metallic　glasses　had　been　studied.　It　is　shown　that　the　Y　addition　can　improve　the　glass　forming　ability　of　Ce-Cu-Al-Nb　alloys.　The　Ce67.5Cu18Al11Nb1.5Y2　sample　exhibits　the　largest　supercooled　liquid　region　ΔTx=97　K,　and　the　lowest　glass　transition　temperature　Tg=349　K.　All　the　samples　exhibit　brittle　fracture　during　compression　at　298　K.　The　fracture　surfaces　of　samples　are　dominated　by　vein-like　patterns.　However,　all　the　samples　exhibit　significant　macroscopic　plastic　deformation　during　compression　at　363　K.　The　stress　overshoot　phenomenon　can　be　observed　for　the　samples　with　x=0-2.　The　Ce67.5Cu18Al11Nb1.5Y2　sample　exhibits　the　lowest　flow　stress　and　the　extended　strain　platform,　which　are　favorable　for　the　plastic　working.　The　Y　addition　can　improve　the　corrosion　resistance　of　Ce-Cu-Al-Nb　alloys,　and　the　Ce67.5Cu18Al11Nb1.5Y2sample　has　the　best　corrosion　resistance.　©,　2014,　Editorial　Office　of　Transactions　of　Materials　and　Heat　Treatment.　All　right　reserved.
