Complex concentrated alloys include five or more elements, at least one of which is ruthenium. Example complex concentrated alloys can include nickel and chromium, iron, ruthenium, molybdenum, and/or tungsten. Example complex concentrated alloys have single phase microstructure of face centered cubic (FCC) and can be homogenous. Example complex concentrated alloys can exhibit improved corrosion resistance.

Complex concentrated alloys: materials, methods, and techniques for manufacture

Aluminum alloys are provided. The alloys can include one or more of zinc, magnesium, copper, zirconium, yttrium, erbium, ytterbium, scandium, silver, and the balance of aluminum and incidental elements and impurities. The alloys can be used for additive manufacturing of various articles, such as aircraft components.

Aluminum alloys

Magnesium alloys comprising a long period stacking order (LPSO) phase having an 14H-i or an 18R-i structure are provided. The alloys comprise magnesium as a majority element, a first alloying element that is larger than magnesium and a second alloying element that is smaller than magnesium.

Magnesium alloys having long-period stacking order phases

Magnesium alloys comprising a long period stacking order (LPSO) phase having an 14H-i or an 18R-i structure are provided. The alloys comprise magnesium as a majority element, a first alloying element that is larger than magnesium and a second alloying element that is smaller than magnesium. The first alloying elements include non-rare earth elements.
