Structure and physical and mechanical properties of aluminum alloy A7 reinforced with basalt fibers

A study was conducted to examine the effect of basalt fibers, at a concentration of 5% by weight, on the structure and physical and mechanical properties of A7 aluminum alloy. The combination of ultrasonic and vibration treatment of the aluminum melt and the strengthening effect of basalt fibers increased the tensile strength, yield strength, and elongation to 83 MPa, 33 MPa, and 40%, respectively. The study also recorded a slight decrease of 3% in electrical conductivity.
