Effect of Heat Treatment on Mechanical Properties of Al-1.5Cu-9.5Zn-3Mg Rapidly Solidified Alloy


Ribbons with the composition Al-1.5Cu-9.5Zn-3Mg were prepared by melt spinning technique. Microhardness and tensile strength were measured. The melt spun hardness and ultimate tensile strength values were as high as 291 HV and 660 MN/m2, respectively. Hardness values are relaxed to lower values on prolonged thermal annealing to around 50%. X-ray diffraction lines corresponding to Cu, Zn and Mg were disappeared for the as melt spun ribbons, which indicates a complete solubility of these element in Al matrix. On prolonged thermal annealing these alloying elements were precipitated.
