Influence of Ag and Co additions on glass-forming ability, thermal and mechanical properties of Cu–Zr–Al bulk metallic glasses
Abstract
In this study, the effect different amounts of Ag and Co have on thermalstability, phase formation and mechanical properties of theglass-forming alloys (Cu<sub>0.5</sub>Zr<sub>0.5</sub>)<sub>95−x−y</sub>Al<sub>5</sub>Ag<sub>x</sub>Co<sub>y</sub> (2≤x≤5 and 0≤y≤2) and Cu<sub>47.5−y</sub>Zr<sub>47.5</sub>Al<sub>5</sub>Co<sub>y</sub>(0≤y≤2) was investigated, respectively. The addition of Ag increasesthe glass-forming ability (GFA) of the alloys by enhancing the stabilityof the undercooled melt and by simultaneously reducing the stability ofthe B2 CuZr high-temperature phase. Co instead, has the oppositeeffect. It leads to an increased thermal stability of the B2 phase, aswell as a decreased stability of the undercooled melt and, consequently,lowers the GFA of the alloys. Moreover, a metastable big cube phaseprecipitates in some alloys stabilized by oxygen, which is introducedduring casting. There is a strong interdependence between the phaseformation and the tendency of the present alloys to vitrify. Thiscorrelation can be captured by the K-parameter (Song et al. 2011 [1])calculated from the respective transformation temperatures. The plasticstrain of the present ternary, quaternary and quinary alloys reflectsthe GFA as well: the higher the tendency to form a glass, the smallerthe plastic strain. Once B2 crystals precipitate in the glass, theplasticity is enhanced significantly.
