Ultrasonic vibrations prior to high pressure die-casting of AA7075 Haghayeghi, A. Heydari, P. Kapranos, “Ultrasonic vibrations prior to high pressure die-casting of AA7075”, Vol.153, 2015, PP.175-178. The effects of introducing ultrasonic vibrations prior to high pressure die casting have been experimentally investigated. Results suggest reductions of up to 73% in grain size and…
