Abstract
The structure and mechanical properties of Ti43.2Zr7.8Cu40.8Ni7.2Co1 alloy cast into a massive copper mold are studied. It has been shown that, after the fast cooling of the alloy, the structure consists of amorphous matrix and crystal particles distributed in the matrix; hence, the alloy displays high strength (higher than 1600 MPa) and relatively high plasticity (1%). Modeling the strain of the alloy using the finite elements method has shown that the crystal particles in the amorphous matrix are effective barriers for the propagation of shear bands, thus stimulating nucleation and the development of new shear bands and increasing the plasticity of the material in general.
