Abstract

The glass-forming ability and mechanical properties of (Fe, Co)-(Cr, Mo)-(C, B)-Tm glassy alloys have been investigated. The (Fe, CO)48Cr15Mo14C15 B6Tm2 glassy alloys were prepared in a cylindrical form with a diameter of 18 mm. The largest supercooled liquid region before crystallization in (Fe1-xCox)48 Cr135Mo14C15B6TM2 alloys is 90 K for Co48Cr15 Mo14 C15B6Tm2. These glassy alloys have high fracture strength of over 4100 MPa for the entire composition range and the strength level is almost independent of Co content. The combination of high strength and high glass-forming ability indicates high possibility of applying the (Fe, Co)-(Cr, Mo)-(C, B)-Tm glassy alloys to various industrial materials.
