“…However, some challenges such as poor corrosion resistance and low room-temperature formability limit the widespread structural applications of Mg alloys in the transportation industry. [10][11][12][13][14][15] Recently, a novel process-roll cladding-was considered to improve the corrosion resistance and formability of Mg alloys. 16,17 Specifically, Al-cladding of Mg alloy sheet could combine the superior corrosion resistance and formability of Al with the high strength-to-weight ratio of Mg substrate.…”

“…For OM observation, the compressed samples were cut to thin plates with a thickness of 1 mm parallel to along the compression axis at the center and then mechanically polished and subsequently etched in an acetic picral solution, i.e. 2.1 g picric acid + 5 mL water + 5 mL acetic acid + 35 mL ethanol [18]. For SEM and TEM analysis, the samples compressed were punched into 3 mm in diameter and prepared with an ion milling method after mechanically grinded.…”

The development behaviors of ultrafine grains (UFGs) due to continuous dynamic recrystallization (cDRX) were investigated in hot compression of a Mg-4Y-2Nd-0.2Zn-0.5Zr alloy pretreated in solution and subsequently peak-aging. In the aging sample containing statically precipitated particles (SPPs), the occurrence of cDRX starts to take place at medium to high strains, and finally a stable size of UFGs are fully developed in a whole volume. In the as-solution sample with no SPPs, by contrast, the size of UFGs evolved increases rapidly at lower strains, slowly at medium strains and then finally shows a bimodal distribution in high strain. In the latter, smaller grains accompanying with an incomplete formation of UFGs are developed by any effect of dynamically precipitated particles (DPPs). The microtexture evolved is effectively randomized in the regions of UFGs, leading to the formation of a weaker texture. The tensile elongation of the aging sample, with SPPs and a fully developed UFGs, was around 17.4 %. This was much higher than that of the as-solution one, with no SPPs and an incompletely developed UFGs, that was 11.8 %, which might result from the more randomized texture due to fully developed UFGs.

“…[11][12][13][14][15][16] It has been reported that the fuel efficiency of passenger vehicles can be enhanced by 6-8% for each 10% reduction in weight [17]. Magnesium (Mg) alloy, as the lightest structural metallic material with a density of 30% less than aluminum and one fourth of steel, has been increasingly used in the transportation industry to reduce the weight of motor vehicles [11,12,[18][19][20][21][22]. However, the concerns about poor corrosion resistance and low room-temperature formability of Mg alloys limit a widespread structural application in transportation industry [13][14][15][16][17][18][19][20][21][22][23].…”

During the last few years ultrasonic welding has become significant attention regarding its suitable applications in comparison to traditional welding techniques. Bonding of dissimilar materials has always been a challenging task due to poor control on grain size and sensitive mechanical properties that could have been made by joining with traditional welding techniques. Moreover, joining dissimilar materials such as Aluminum/steel, metal/glass, Aluminum/copper had not been achieved without the usage of ultrasonic welding technique. This work presents a review of literature regarding the usage of ultrasonic welding technique in many applications. Additionally, this paper provides different examples and applications of ultrasonic welding technique and its application. Main advantages of this technique are, clean and undamaged exterior parts of weld, power savings, stable and strong bond, time efficiency
