Aluminum-manganese alloy Britannica

Shechtman and his coworkers mixed aluminum and manganese in a roughly six-to-one proportion and heated the mixture until it melted. The mixture was then rapidly cooled back into the solid state by dropping the liquid onto a cold spinning wheel, a process known. Read More.

Aluminum-Magnesium Alloys - an overview ScienceDirect Topics

The oxidation of aluminium–magnesium in dry air or oxygen follows a parabolic law until about 400°C and then a linear law. In this linear phase, the oxidation rate is controlled by the diffusion of cations, mainly Mg 2+, through the MgO.Al 2 O 3 film. This is the reason for depletion of magnesium at the metal/oxide interface (Fig. B.3.7).

How and why alloying elements are added to aluminum

Manganese (Mn) 3xxx – The addition of manganese to aluminum increases strength somewhat through solution strengthening and improves strain hardening while not appreciably reducing ductility or corrosion resistance. These are moderate strength nonheat-treatable materials that retain strength at elevated temperatures and are seldom used for major structural applications.
