| Popis: | In this research work, an investigation is done to explain the influence of precipitation hardening treatments by their stages of solution heat treatment, quenching, and artificial ageing on tensile strength, yield stress, absorbed energy of impact, and microstructural changes of Aluminum alloy AA6061. This alloy has a wide range of applications in industry and daily life. Results showed that the best temperature of solution heat treatment is (540)°C and the best artificial ageing temperature is (200)°C when the alloy is subjected to solution treatment at temperature of (540)°C. Also, results clarified that the maximum values of the tensile strength and yield stress are (290) MPa and (270) MPa respectively, in specimens artificially aged at (200)°C for (6) hours, whereas the maximum value of impact toughness is (27) Joules in specimens artificially aged at (200)°C for (2) hours due to the refinement of the intermetallic compound Magnesium Silicide (Mg2Si) as in XRD patterns and SEM images. The samples with highest values of tensile properties have the lowest values of impact toughness. |
