Abstract

Al-Mn-Zn ternary system is experimentally investigated at 400∘C using diffusion couples and key alloys. Phase relationships and homogeneity ranges are determined for binary and ternary compounds using EPMA, SEM/EDS, and XRD. Reported ternary compound T3 (Al11Mn3Zn2) is confirmed in this study and is denoted as t2 in this paper. Two new ternary compounds (t1 and t3) are observed in this system at 400∘C. t1 is determined as a stoichiometric compound with the composition of Al31Mn8Zn11. t3 has been found to have homogeneity range of AlxMnyZnz (x = 9–13 at%; y = 11–15 at%; z = 75–77 at%).The binary compounds Al4Mn and Al11Mn4 exhibit limited solid solubility of around 6 at% and 4 at% Zn, respectively. Terminal solid solution Al8Mn5 is found to have maximum ternary solubility of about 10 at% Zn. In addition, ternary solubility of Al-rich B-Mn' at 400∘C is
determined as 4 at% Zn. Zn-rich B-Mn'' has a ternary solubility of 3 at%Al.The solubility ofAl inMn5Zn21 is measured as 5 at%. Based on the current experimental results, the isothermal section of Al-Mn-Zn ternary system at 400∘C has been constructed.
