“…12. In addition, the region I is observed for the diffusion of 60Co(55)(60) 51Cr(55) 59Fe(56)(60) and 115mCd (56) in aluminum and the diffusion of 110Ag (56) in aluminum alloyed with 1at% copper or 1at% silver. Both the regions I and III are observed for the diffusion of 147Nd(60) in aluminum.…”

“…The isotope effect of 110 Ag diffusion in Al was measured as a function of diffusion temperature by Bartdorff and Peimers [30] using the sectioning and counting method. Alexander and Slifkin [31] contributed to the measurement of 100 Ag diffusion in single crystals of Al and dilute Al alloys in the temperature range of 615-883 K with the tracer sectioning technique. Employing the SIMS (Second Ion Mass Spectroscopy) technique, Gontier-Moya et al [32] investigated the diffusivities of Ag in single Crystalline Al at 1073-1423 K. The diffusivities of Ag in polycrystalline Al were measured at 723-898 K by Khan et al [33] using the sectioning and counting method.…”

“…The tracer diffusivities of Ag in pure Al and fcc Al-Ag alloys were measured by several groups of authors, [30][31][32][33][34][35][36][37] while the impurity diffusivities of Al in Ag were measured only by Fogel'son et al [38] due to the fact that 26 Al has a very low specific activity while the measurement requires a thick deposition layer. The isotope effect of 110 Ag diffusion in Al was measured as a function of diffusion temperature by Bartdorff and Peimers [30] using the sectioning and counting method.…”

Based on various experimental diffusivities of fcc Al-Ag-Zn alloys available in the literature and the thermodynamic parameter evaluated in the present work, atomic mobilities of Al, Ag and Zn in the fcc Al-Ag-Zn system were assessed as a function of composition and temperature with the aid of DICTRA software. Comparison between the calculated diffusivities and the corresponding experimental data indicates that the presently obtained atomic mobilities can reproduce most of the diffusivities, such as tracer diffusivities, impurity diffusivities and interdiffusivities in both binary and ternary systems. The reliability of the atomic mobilities was further verified via comparisons between the model-predicted concentration-distance profiles of the binary and ternary diffusion couples and the experimentally measured ones. Good agreement between the calculated and the measured concentration-distance profiles indicates that the presently obtained atomic mobilities are reliable. The diffusion paths can be also reproduced by the presently obtained atomic mobilities.

“…Ci(x,0)=Ci0,x>0, (30) and (31) Equations (20) and (21) have been used to calculate a number of diffusion profiles and paths. Figures 5(a), (b) and 6 show the superpositions of the actual experimental data and the calculated diffusion profiles and paths.…”

diffusion profiles have been determined, and then the diffusion paths have been drawn in the ternary composition triangle. The interdiffusion coefficients and have been determined by Matano's method. The four coefficients have been found to be sensitive to the solute concentration. The diffusion profiles and paths have been also calculated by the solution of Fujita et al. and by the finite-difference method using the experimental values of the four interdiffusion coefficients. Good agreements have been found between the experimental and calculated both of them. (Received April 16, 1983) Keywords:interdiffusion, aluminum-silver-zinc alloy, diffusion couple, interaction parameter, finite-difference method Many investigations of diffusion have been performed on binary alloys. On the other hand, only about twelve studies on ternary diffusion have been reported in substitutional solid solution of Al-, Cu-and Fe-alloys(1)-(12), since interdiffusion in a binary alloy can be described by only one interdiffusion coefficient D and four interdiffusion coefficients are necessary to describe the interdiffusion in a ternary alloy.The purpose of this study is to investigate the solution of the Al-Ag-Zn ternary system at 832K. Preparation of diffusion couplesEleven diffusion couples were prepared. Two of them were those for the binary diffusion. Chemical compositions of couples are listed in Table 1. The alloys were prepared from 99.996%Al, 99.9%Ag and 99.996%Zn, and then homogenized at 789K for 690ks. Some ing in sodium hydroxide and phosphoric acid solution, the rods were inserted into the holes of the blocks, in order to make the diffusion marker.The composite metals were heated at 783K for 600s, and then rolled into 7.6mm in thickness. The rolling is practical and also has the advantage that the oxide film at the interface between the alloys is broken up and distributed over a much larger area(13)• The rolled metals were cut into 5mm in width as the diffusion Table 1 Terminal compositions of the diffusion couples.
