Abstract

(Ti-Zr)-(Cu-Ni-Co) bulk metallic alloys containing 1000 mass ppm of boron 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 and different diameters were prepared and investigated. Some of the prepared bulk glassy-crystal composite samples showes rather good properties: the compressive strength of 1800-2500MPa and compressive plasticity up to 13.5%.
