Advanced aluminium alloys for aircraft and aerospace applications

Durability and Corrosion of Aluminium and Its Alloys: Overview, Property Space, Techniques and Developments

“…Li is soluble in aluminium to ~ 4 wt% (corresponding to ~ 16 at%). As these alloys of high specific strength and stiffness readily respond to heat treatment, research and development has intensified due to their potential for widespread usage in aerospace applications (Lavernia and Grant 1987;Dorward and Pritchett 1988;Giummarra, Thomas et al 2007). Based on the impressive lightweight of such alloys, present day aircraft are comprised of some portion of Al-Li based alloys (modern generations of which actually include low Li levels and hence are nowadays designated as 2xxx alloys (Ambat and Dwarakadasa 1992;Garrard 1994;Semenov 2001;Giummarra, Thomas et al 2007).…”

Aluminium pm: alloys and composites development and enhancement

“…Pese a que estos materiales compuestos presentan propiedades superiores a las aleaciones que se vienen empleando tradicionalmente, el uso de estos MMCs en ciertas aplicaciones ingenieriles es aún dudoso. Con todo, las excelentes propiedades de estos MMCs los hace los materiales ideales para el futuro debido a la variedad de aplicaciones estructurales, electrónicas, aeroespaciales, en automoción y en defensa [27][28][29][30][31][32][33][34][35][36][37][38] .…”

“…La mayor parte de las investigaciones sobre los MMCs se han llevado a cabo para los materiales compuestos base aluminio (AMCs), con el objetivo de mejorar sus propiedades mecánicas mediante la incorporación de cerámicos tales como óxidos, carburos o nitruros en la matriz metálica [34][35][36][37][38] .…”

Film dissolution kinetics of aluminium at precisely adjusted pH‐values

“…Aluminium is used in many different fields like nuclear reactors, aerospace, automotive, construction, aluminium alloys, coatings and metal/air batteries . At neutral pH values, a thick oxide film is formed, which acts as barrier layer .…”
