Abstract The as-cast Zr 57 Ti 8 Nb 2.5 Cu 13.9 Ni 11.1 Al 7.5 glass-quasicrystalline composite exhibits high strength, good elasticity but no macroscopic room temperature plastic deformability. Significant improvement of plastic deformability to a strain of about 5 % can be achieved after cold rolling of the as-cast material. This behavior can be ascribed the anisotropic and inhomogeneous stress distribution developing during the mechanical test along with the creation of an extensive system of shear bands. Keywords.
