A　series　of　rod　samples　with　diameter　of　3　mm　(Zr0.55Al0.10Ni0.05Cu0.30)(100-x)Fe-x(x=0,　1,　2,　3,　4)　were　prepared　by　magnetic　suspend　melting　and　copper　mold　suction　casting　method.　The　effects　of　a　small　amount　of　Fe　on　glass　forming　ability(GFA)　and　mechanical　properties　of　Zr55Al10Ni5Cu30　bulk　metallic　glass　(BMG)　were　investigated.　The　results　show　that　the　addition　of　an　appropriate　amount　(less　than　3%,　mole　fraction)　of　Fe　enhances　GFA,　as　indicated　by　the　increase　in　the　reduced　glass　transition　temperature　T-rg(=T-g/T-l)　and　the　parameter　gamma(=　T-x/(T-g+T-l))　with　increasing　Fe　content,　and　GFA　gets　deteriorated　by　further　Fe　addition　(4%).　The　addition　of　Fe　also　effectively　improves　the　compressive　plasticity　and　increases　the　compressive　fracture　strength　in　these　Zr-based　BMGs.　Compressive　tests　on　BMG　sample　with　3　mm　in　diameter　and　6　mm　in　length　reveal　work-hardening　and　a　certain　plastic　strain　in　the　alloy　containing　2%　Fe.　The　BMG　composite　containing　4%　Fe　also　exhibits　a　high　fracture　strength　along　with　significant　plasticity.
