Effects of ultrasonic treatment on microstructures of AZ91 alloy

Influence of ultrasonication power on grain refinement, mechanical properties and wear behaviour of AZ91D/nano-Al2O3 composites

“…The Nevertheless, the weaker intensity of β-Mg 17 Al 12 phase is seen compared to that of the untreated composite. This is attributed to the effective dissolution of the β-Mg 17 Al 12 in the matrix due to ultrasonic treatment [11,12].…”

“…UST eliminates the nanoparticle clusters of agglomeration and efficiently disperses them throughout the metal matrix by 'cavitation effect'. Cavitation effect is a phenomenon which forms and implodes micro vapour bubbles due to a sudden change in pressure in the melt [11][12][13]. The multiplied implosion of the bubbles produces high temperature and pressure spots in the melt.…”

Investigation into the Extrudability of a New Mg-Al-Zn-RE Alloy with Large Amounts of Alloying Elements

“…Table 4). Mg17Al12 and Al8Mn5 were the common intermetallic compounds in commercial Mg-Al-Zn alloys with a high Al content [48,49]. Al11La3 and Al2Gd were the compounds whose formation was due to the addition of rare earth elements of La and Ga [38,[50][51]] to the Mg-Al-Zn base alloy.…”

Enhanced carbide tool life by the electromagnetic coupling field for sustainable manufacturing

“…Orgiu et al [21] found a vacuumed electromagnetic environment can improve the material performance. Wang et al [22] processed an unreformed TC11 alloy with a pulsed magnetic field, a pulse current, and a pulse electromagnetic alloy structure to explore their influences on structure, lattice parameter dislocation, and microhardness. After the processes, the content of the primary alpha phase in the alloy was increased, and the dislocation entanglement was decreased.…”
