Abstract
The effect of small lanthanum additions on the structure and the phase composition of a commercial magnesium cast ML5pch alloy (Mg–Al–Zn–Mn system) in the as-cast and heat-treated states is studied. The addition of lanthanum is found to result in the formation of a new intermetallic Mg17(La,Al)2 phase, to improve the structure of the ML5pch alloy, and to increase its relative elongation and yield strength in the heat-treated state.
