A　powder　metallurgy　technology　was　developed　to　prepare　Ti50Cu23Ni20Sn7　bulk　metallic　glasses　(BMGs).　Firstly,　amorphous　powder　was　prepared　by　mechanical　alloying　(MA)　method　successfully　after　being　milled　for　30　h.　Phase　transformation　of　the　as-milled　powder　was　characterized　by　X-ray　diffraction　(XRD).　Morphology　of　the　as-milled　amorphous　powder　was　observed　by　scanning　electron　microscopy　(SEM).　Onset　temperature　of　glass　transformation　and　onset　temperature　of　crystallization　(T-x　and　T-g)　of　the　as-milled　amorphous　powder　were　evaluated　by　differential　scanning　calorimeter　(DSC).　Secondly,　the　as-milled　amorphous　powder　was　then　consolidated　by　spark-plasma　sintering　(SPS)　method　into　a　specimen　with　the　shape　of　cylindrical　stick,　with　a　diameter　and　height　of　about:　20　and　10　mm,　respectively.　The　SPS　experiment　was　conducted　under　a　pressure　of　500　MPa　at　a　heating　rate　of　40　K/min,　sintering　and　holding　for　1　min　at　the　temperature　of　763　K.　It　was　confirmed　that　the　as-milled　powder　is　of　fully　amorphous　however　the　consolidated　specimen　shows　to　be　an　amorphous　matrix　with　partial　crystallization.　Compressing　strength,　Young＇s　modulus,　micro-hardness,　friction　and　density　of　the　consolidated　specimen　are　about　975　MPa,　121　GPa,　13　GPa,　0.12　and　6599　kg/m(3),　respectively.　Fractograph　of　the　specimen　appears　to　be　shear　fracture　and　very　few　defects　can　be　seen　from　the　picture　of　SEM.　(C)　2008　Elsevier　B.V.　All　rights　reserved.
