<jats:title>Abstract</jats:title>
<jats:p>The phenomena occurring in the microstructure of the material are responsible for its macroscopic properties, such as strength, hardness, and toughness. Strengthening phases with the appropriate composition and characteristics increase the strength of the alloy. However, excess brittle intermetallic phases may cause problems with cracking and plasticity of the material. The amount and morphology of those particles are related to the chemical composition of the alloy. Simulation of tensile loading of the microstructure of three different 2024 aluminium alloys shows how the distribution of intermetallic phases affects stress states in the material. The results show that variations in the amount of the alloying additions in the range described by the standard can influence the deformation mechanisms in the material.</jats:p>
