Isochronal tensile stress relaxation of a bulk metallic glass

Isochronal tensile stress relaxation of a bulk metallic glass

Isochronal stress relaxation of bulk Zr 52.5Ti 5Cu 17.9Ni 14.6Al 10 starts at about 400 K and ends below the glass transition temperature. The kinetics of stress relaxation has been analytically described to be a result of stress-oriented irreversible structural relaxation with distributed activatio...

Zusammenfassung:Isochronal stress relaxation of bulk Zr 52.5Ti 5Cu 17.9Ni 14.6Al 10 starts at about 400 K and ends below the glass transition temperature. The kinetics of stress relaxation has been analytically described to be a result of stress-oriented irreversible structural relaxation with distributed activation energies. Satisfactory agreement between experimental and calculated data has been shown.
