High strength materials have been great demands for structural materials, such as components in airplanes or cars, especially in electric vehicles. Aluminium alloys have high strength-to-weight ratio, leading to less energy consumption of vehicles and weight reduction of battery enclosures [1]. Al-Mg-Si(-Cu) alloys (6XXX series) are heat treatable alloys and play an important role in various industries due to their moderately high strength and good corrosion resistance, superior to other heat treatable aluminium alloys. The main strengthening mechanism of the alloy derives from the precipitation hardening. There are many factors that directly affect to precipitation hardening: (1.) Chemical composition of alloys such as alloying elements and (2.) Processing such as deformation and heat treatment [2].

高强度材料对结构材料（例如飞机或汽车的组件，尤其是电动汽车中）的需求非常重要。铝合金具有高强度的比率，导致车辆的能源消耗较小和电池外壳的减轻重量[1]。 Al-Mg-Si（-cu）合金（6xxx系列）是可热处理的合金，由于其中等高强度和良好的耐腐蚀性，在各个行业中起着重要作用，优于其他可热处理的铝合金。合金的主要加强机制来自降水硬化。有许多因素直接影响降水硬化：（1.）合金的化合物组成，例如合金元件和（2.）处理，例如变形和热处理[2]。
