“In the field of materials science, researchers have used ultrasound and mechanical vibration coupled field assisted in-situ synthesis technology and squeeze casting technology to prepare heat free Al3Ti/Al Mg Mn composites. The effects of different Ti contents on the microstructure and mechanical properties of Al3Ti/Al Mg Mn composites under vibration and pressure fields were studied. The results indicate that the Al3Ti particles in the Al3Ti/Al Mg Mn composite material are square shaped and evenly distributed. The tensile strength and yield strength of composite materials increase with the increase of Ti content, while the elongation rate decreases. This is due to the grain refinement and second phase strengthening effect caused by Al3Ti. In addition, Al3Ti leads to an increase in the porosity of the alloy and acts as a crack source during the tensile process, resulting in a decrease in the plasticity of the composite material. The composite material with a Ti content of 3% has ideal mechanical properties, with a tensile strength of 282 MPa, a yield strength of 162 MPa, and an elongation of 15.5%.”
