This paper builds on the “Grain Refinement of Mg Alloys” published in 2005 and reviews the
grain refinement research on Mg alloys that has been undertaken since then with an …

Refinement of grains and intermetallic phases in the as-solidified alloy structure offers
uniform structural properties, eliminates or minimizes common solidification defects …

This study shows that a eutectic Al–12Si alloy with controllable ultrafine microstructure and
excellent mechanical properties can be achieved by using selective laser melting and …

This is the first monograph to comprehensively cover the effect of using power ultrasound to
refine and solidify aluminium and magnesium alloys. The author is widely regarded as a …

Ultrasound processing of metal alloys is an environmental friendly and promising green
technology for liquid metal degassing and microstructural refinement. However many …

Laser engineered net shaping (LENS), a laser beam deposition additive manufacturing
method, has been utilized as a key technology in the direct manufacturing or repairing of …

Ultrasonic irradiation during solidification has emerged as an effective means of structural
refinement for both metallic and non-metallic materials. A number of mechanisms have been …

This paper focuses on acoustic streaming free jets. This is to say that progressive acoustic
waves are used to generate a steady flow far from any wall. The derivation of the governing …

Although the icosahedral quasicrystal phase found in Mg-Zn-Y alloys has some outstanding
characteristics, the coarse α-Mg dendrites and the agglomeration of the secondary phases …

Ultrasonic vibration was introduced into the solidification of the AZ91 magnesium alloy. The
coarse dendrite microstructure solidified in the AZ91 alloy without any ultrasonic vibration …
