Study of the effect of heat treatment on the structure, phase composition, and mechanical properties of ML12 alloy with AlN nanoparticles added

The study examines the effect of AlN nanoparticles with concentrations of 0.1, 0.5, and 1 wt.% on the structure and properties of the ML12 magnesium alloy. It is shown that additives of 0.5 and 1 wt.% provide a uniform grain structure (average grain size of 46 and 54 μm), while heat treatment promotes homogenisation without changing the average grain size. The maximum increase in strength (up to 212 MPa) and ductility (up to 19.7%) is achieved at 0.1 wt.% AlN. It has been established that the dominant strengthening mechanism is dispersion strengthening.
