Tuning homogenization of high-strength aluminum alloys through thermodynamic alloying approach

The alloy design and homogenization processes are intimately associated with the microstructure, phase composition and performance for Al-Zn-Mg-Cu alloys. The microstructures and phase composition of a series of Al-Zn-Mg-Cu alloys before and after the homogenization treatments were investigated along with thermodynamic calculation to...

Ultrasonic processing of aluminum alloys

The research in ultrasonic processing for metallurgical application shows a promising influence on improving casting properties of aluminium alloys. The principle of ultrasonic processing is introduction of acoustic waves with a frequency higher than 17 kHz into liquid metal. Several promising beneficial effects caused by ultrasonic processing...
