A kind of novel Ti-based composites was developed by introducing different amounts of carbon element to the Ti50 Cu23 Ni20 Sn7 bulk metallic glass forming alloys. The thermal stability and microstructural evolution of the composites were investigated. Room temperature compression tests reveal that the composite samples with 1 % and 3 % (mass fraction) carbon additions have higher fracture strength and obvious plastic strain of 2 195 MPa, 3.1%and 1 913 MPa, 1.3 % respectively, compared with those of the corresponding carbon-free Ti50 Ni20 Cu23 Sn7 alloys.The deformation mechanisms of the composites with improved mechanical properties were also discussed.
