为了保证现代化设备的寿命和可靠性,B95型高强度铝合金板材应具有较高的强度、断裂韧性和抗蚀性,可通过以下几种途径来达此目的:限制杂质铁和硅的含量以及采用新合金B95п_ч、B95_(оч),从而在保持原有强度的同时提高了塑性和抗断裂的能力;制定新的使强化相聚集的时效制度T2和T3,以保证较高的抗剥落腐蚀和抗应力腐蚀开裂的性能,并在略降低强度的条件下改善断裂韧性。
To ensure the longevity and reliability of modern equipment, B95 high-strength aluminum alloy sheet should have high strength, fracture toughness and corrosion resistance, which can be achieved through the following ways: to limit the content of iron and silicon impurities and The new alloys B95 and B95_ (оч) are used to enhance the plasticity and fracture resistance while maintaining the original strength. New aging regimes T2 and T3 for the consolidation of strengthening phases are developed to ensure high resistance to exfoliation corrosion and Resistance to stress corrosion cracking and improved fracture toughness with slightly reduced strength.
