The influence of shock wave surface treatment on vibration behavior of Semi-Solid State Cast Aluminum—Al₂SiO₅ composite

The semi-solid state casting procedure was used to manufacture as-cast AA5083, 1 and 2 wt.% of aluminosilicate reinforced composite material. After solidification, developed as-cast materials were subjected to shock wave treatment in the subsonic wind tunnel. Various techniques were used to evaluate the change in shock wave exposure, including mechanical and structural analysis, which is a field dedicated to the study of vibrations and other material properties. The research methods involved developed material grain structure and surface morphology, such as field emission scanning electron microscope, X-ray diffraction, and the energy dispersive method. This study shows that the microhardness value of the matrix material is increased before and after exposure to shock wave treatment compared to the developed composite material. The natural frequency of the developed composite increases as a result of the addition of aluminosilicate reinforcement before and after the shock wave. In addition, the shifting of frequency mechanism is studied to know the influence of shock wave surface treatment. The results obtained show the potential of the application of this material in the area of robotic parts.
