(Ti-Zr)-(Cu-Ni-Co) bulk metallic alloys were investigated in the present work. Taking compositional formula (Ti-Zr) 49.5+x(Cu-Ni) 49.5-xCo 1 as a basis, we increased the content of Ti and Zr elements and decreased the content of Cu and Ni with the purpose of production of crystal-glassy composites. Such a kind of approach may allow combination of high strength of glassy alloys and good plasticity of crystalline alloys in these composite materials. According to this approach a large number of the alloys of different composition were prepared and investigated. Ti 43.2Zr 7.8Cu 40.8Ni 7.2Co 1 bulk glassy-crystal composite sample showed the compressive strength of 1800 MPa and plasticity of about 5%. The effect of Y addition on the glass-forming ability and mechanical properties of the studied alloys was also investigated.
