Most of the mechanical components are exposed to environmental attacks and different loading conditions, e.g., internal pressure, high-temperature gradient, and angular velocity. Therefore, investigating their mechanical behavior under operating conditions is necessary to gain higher efficiency and less mechanical failure. Due to the vast industrial applications of Aluminum (Al) alloys, in this paper, the tensile and creep behavior of Al 7075-T6 were studied at elevated temperatures. The Norton-Power Law (NPL) equation was considered as a creep constitutive equation to estimate the creep behavior of Al 7075-T6 alloy. To this aim, experimental uniaxial creep tests were carried out to derive creep constitutive parameters. These parameters were used to predict the creep behavior of different structures, such as Al vessels. The reference stress method (RSM) and developed constitutive model were utilized to plot graphs that provide design conditions and optimum creep lifetime for Al vessel subjected to combined rotation and internal pressure. These graphs can be employed in industrial applications to facilitate the design process of Al vessels.

大多数机械组件都受到环境的攻击和不同的负载条件，例如内部压力，高温梯度和角速度。因此，研究其在工作条件下的机械性能对于获得更高的效率和更少的机械故障是必要的。由于铝（Al）合金在工业上的广泛应用，本文对Al 7075-T6在高温下的拉伸和蠕变行为进行了研究。诺顿幂定律（NPL）方程被视为蠕变本构方程，用于估计Al 7075-T6合金的蠕变行为。为此，进行了实验性单轴蠕变试验，以得出蠕变本构参数。这些参数用于预测不同结构（例如Al容器）的蠕变行为。利用参考应力法（RSM）和建立的本构模型绘制曲线图，这些曲线图为铝容器在旋转和内部压力共同作用下提供了设计条件和最佳蠕变寿命。这些图可用于工业应用，以方便Al容器的设计过程。
