Effect of heat treatment on mechanical properties of Al 7075 T6

Among the compounds Al, Series 2*** and 7*** due to achieve the desired mechanical properties of particular importance Are important. In the meantime, heat treatable alloy Al7075 including climbing alloysIs having a hard sediment. One of the most common heat treatment cycles performed on Al7075T6 heat treatment there is. In this study, samples of Al7075 alloy initially in a separate step Homogenization, and then dissolved at a temperature of 470-485°C for time min75 It fits again in the T6 temperature of 130℃ 160,190 and 220°C Vbmdt time 4h and quenched in water under conditions of heat treatment were tested. The final data review and analysis They conclude that the optimum temperature for solution temperature 485℃ 130min duration of temperature Is optimal because there is not enough time for uniform distribution of alloying elements result in step T6 in Brinell hardness of 143.35 maximum 220℃ temperature is achieved.
