An X-Ray Diffraction Line Profile Analysis in Cold-Worked Fcc Ag-lSn-Zn Alloys: Role of 1 Wt Pet Sn A.K. MAITY and S.P. SEN GUPTA Recently, we have undertaken a study on the states of cold-worked deformed materials with fcc Cu-Ni-Zn, 121 Cu-Sn-Zn, t21 and Cu-Mn-ZnTM ternary alloy systems, employing detailed analyses of the X-ray powder diffraction line profiles. In all these systems, the solvent metal is copper, and the additions of transitional solutes Ni, Mn in the solid solution range and also nontransitional solute Sn in the dilute range (to the a-brass system) have been made to obtain a clear picture of the role of the addition of a third component. In the present communication, the studies have been extended to the silverbase alloy system (Ag-1Sn-Zn) to see the role of dilute Sn in binary Ag-Zn. l+~ Five compositions (in weight percent), namely, Ag1Sn-5, 10, 15, 20, and 25Zn, were prepared in the usual wayt5,61 f
