Algorithmic analysis of the microstructure of aluminum alloy

In this paper, the microstructure and mechanical properties of aluminum alloy materials were studied. The microstructure simulation program of Voronoi algorithm was written with Python, and the program was imported into ABAQUS finite element software to establish the grain model of aluminum alloy. The finite element model of grain structure was established. The results show that the stress concentration coefficient of a single inclusion particle decreases first and then increases with the increase of elastic modulus. Compared with a single inclusion particle, the stress concentration of two inclusion particles will increase, and the shape, quantity and distribution of inclusion particles have influence on the microstructure stress concentration.
