轻型耐腐蚀铝合金可以作为钢和钛合金的替代材料,但多数铝合金只能用在低于200℃的场合,这意味着它们不能用于高温的场合,如发动机。美国西北大学McCormick工程和应用科学学校的David N.Seidman、David C.Dunand等材料科学与工程研究人员进行了铝与锂(比铝密度低,使材料更轻)和钪(显著强化铝)元素化合,还添加了少量的镱作为强化元素(比钪便宜),研制出一种新型纳米级高强度和耐高温腐蚀铝合金。
Light-weight, corrosion-resistant aluminum alloys can be used as an alternative to steel and titanium alloys, but most aluminum alloys can only be used below 200 ° C, meaning they can not be used in high-temperature applications such as engines. Material science and engineering researchers such as David N. Seidman and David C. Dunand at the McCormick School of Engineering and Applied Sciences at Northwestern University conducted experiments with aluminum and lithium (lower than aluminum and lighter in material) and scandium (significantly strengthened aluminum) Combined, also added a small amount of ytterbium as a strengthening element (cheaper than scandium), developed a new nano-high strength and high temperature corrosion of aluminum.
