The stacking-fault energy in the Ag-In series

Abstract

VThe intrinsic, stacking fault energy has n determined in the Ag-In series using extended nodes, from pure silver to In (e/a = 1.23). Extrinsie faulting has been observed tnroughout

Solid solution softening and enhanced ductility in concentrated FCC silver solid solution alloys

“…In the literature, Ag-Al (7.5 at%) [25], Ag-In (11.5 at%) [26], and Ag-Sn (7.8 at%) [27], concentrated solid solution alloys with similar concentrations were studied under TEM in order to conduct the direct measurement for the stacking fault energy of those alloys from the observations of extended dislocations nodes in the micrographs. To the best knowledge of the authors, there is no direct TEM study reports on Ag-Ga solid solution alloy in the literature.…”

“…intrinsic stacking fault energy of pure Ag, γ Ag , is 21.9 erg/cm 2 , and the values of intrinsic stacking fault energy of solid solution alloys in Ag-Al [25], Ag-In [26] and Ag-Sn [27] systems were plotted as a function of solute concentration in Fig. 11 (a), using the values given in the literatures, as determined by the direct TEM measurements.…”

“…The 11. (a) The variation of the intrinsic stacking fault energy with solute elements concentration in Ag-Al, Ag-In and Ag-Sn systems, using TEM extended nodes observation determined values [25][26][27], (b) the variation of the stacking fault density with solute elements concentration in Ag-Al, Ag-Ga, Ag-In and AgSn systems, determined by XRD measurements [37], (c) the variation of the normalized intrinsic stacking fault energy with solute elements concentration in Ag-Al, Ag-Ga, Ag-In and Ag-Sn systems.…”

Studies of the Effect of Annealing on Extended Dislocation Nodes in Silver‐Tin Alloys

“…Gallagher and Valdr6 [6] reported a significant decrease in the room temperature SFE of silver after annealing foil samples a t 600 O K . Gallagher and Washburn [7] found an irreversible increase in the SFE of two silver-indium alloys after annealing the foils up t o 400 "C. Recently Gallagher and Ku [8] found an irreversible increase in SFE after annealing up to 250 "C in Cu-30% Zn and Cu-7.5% Al. Thomas [9] had previously found that annealing a quenched Cu-30% Zn alloy a t 200 "C caused an increase in the SFE determined from nodes.…”

“…[ll] and Gallagher and Washburn [7] reported that they could find no significant influence of oxygen content on the SFE of silver, although Klein et. al.…”
