    Since Ti-based glassy alloys have high strength and high corrosion resistance, it is useful for an application field of substitution material for biomaterials such as living body bone. For the biomaterial use, the glassy alloys are required to substitute the harmful elements for the human body such as Ni. In the present study, we prepared the Ti47.4Cu 42Zr5.3TM5.3(TM = Co, Fe) glassy alloy sheets by a twin-roller casting method, and investigated their thermal stability and mechanical properties. The prepared alloy sheets had flat surfaces with highly white luster, and exhibited a distinct glass transition typical to a glassy phase. The super-cooled liquid region ATx defined by the difference between the glass transition temperature (Tg) and the onset temperature for crystallization (Tx) is 50 K for the Ni-containing alloy, 36 K for the Co-containing alloy and 32 K for the Fe-containing alloy. All the alloy sheets exhibit good bending ductility and their Vickers hardness is in the range of 590 to 600.
