Molding Creep-Resistant Alloys,sium alloys expressed by their behavior at elevated temperatures. While Mg—Al and Mg—Al—Zn combinations exhibit moderate tensile strength at ambient temperatures, they are all prone to excessive creep when exposed to even low-level loads above approximately 120 °C.作者: Myocarditis 時(shí)間: 2025-3-22 11:58 作者: 牙齒 時(shí)間: 2025-3-22 14:23 作者: 燒瓶 時(shí)間: 2025-3-22 18:29
