Abstract

Multicomponent alloys of Zr50M50,Zr50(M,Ag)50 and Zr50(M,Pd)50(M=Fe,Co,Ni,Cu)can be melt-spun to obtain amorphous ribbons.The maximum thickness for fully amorphous ribbons varies with composi-tion in the range 34-53 μm.In contrast,fully amorphous ribbons are not obtainable for binary Zr50Ni50 or ternary Zr50(Ni,Cu)50 alloys.Heating-induced crystallization occurs through:two stages of amorphous[am]→[am'+B2]→[B2+B33]for Zr50M50;and[am]→[am'+B2]→[B2+AgZr]for Zr50(M,Ag)50;and a single stage of[am]→[B2]for Zr50(M,Pd)50,while no B2 phase is formed for the binary and ternary Zr50Q50(Q=Ni or/and Cu)alloys.As-spun amorphous ribbons have good bending plasticity.Re-markably,Zr50M50 ribbons in tension show 0.22-0.28％plastic elongation and work-hardening(the yield stress is～820 MPa,the fracture stress is～1200 MPa).When cold-rolled at room temperature to 30％reduction in thickness,Zr50Ms0 ribbons show 10％increase in hardness,while retaining good bending plasticity.Cold-rolling induces precipitation of spheroidal B2 and irregular B33 particles,while deforma-tion in tension induces B2,B33 and also plate-like monoclinic precipitates.The B2 and B33 particles form by polymorphic transformation,and include a high density of internal defects.This novel deformation-induced precipitation has not been recognized for any Zr50Q50 binary or ternary alloys.The new multi-component systems are encouraging for future progress as structural amorphous alloys.
