The influence of the addition of Ag to the crystallization and mechanical properties of the amorphous Zr_(65)Al_(7.5)Ni_(10)Cu(17.5-x)Ag_x (x=5, 10 at.%) alloys was investigated. It was found that crystallization takes place through the two-stage process of Am→Am'+icosahedral-phase Zr₂Cu+Zr₂Ni+Zr₂Al₃. The icosahedral particles have a spherical morphology and their sizes range from 10 to 100 ㎚. With the increase in the amount of Ag, thermal instability increases through the simultaneous decrease of T_x and ΔT_x. The σ_f increases significantly from 1560 ㎫ at 0%V_f to 2120 ㎫ at 62%V_f for the 10% Ag alloy.
