Effects of rheo-squeeze casting parameters on microstructure and mechanical properties of AlCuMnTi alloy

► Indirect ultrasonic vibration (IUV) was a new method for making semisolid slurry. ► IUV method has wide application prospects for simple process and high efficiency. ► Rheo-squeeze casting (RSC) samples could achieve better performance. ► Effects of RSC parameters on the microstructure of samples were studied. ► Effects of RSC parameters on the mechanical properties of samples were studied.
