The as-cast Zr57Ti8Nb2.5Cu13.9Ni11.1Al7.5 glass–quasicrystalline composite exhibits high strength, good elasticity but no macroscopic room temperature plastic deformability. Significant improvement in 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.
