Computational design for the wire and arc additive manufacturing process

The world has seen industrial revolutions with advancements in manufacturing technologies. The advancements in Additive Manufacturing (AM) technologies will bring another revolution sooner rather than later. Nowadays, the Wire and Arc Additive Manufacturing (WAAM) process is already used to manufacture large-scale structures such as ship...

Applying multi-pass friction stir processing to refine the microstructure and enhance the strength, ductility and corrosion resistance of WE43 magnesium alloy

Magnesium alloys have many unique properties, mostly benefitting from the low density of magnesium. However, they are not competitive, when compared with other lightweight materials, such as aluminum alloys, particularly in ductility and corrosion resistance. There is a strong need to improve the mechanical properties and corrosion resistance...

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...
