Effect of Intermetallic Compound Layer on Tensile Strength of Dissimilar Friction-Stir Weld of a High Strength Mg Alloy and Al Alloy

“…7) By using RCP, high strength Mg alloys with fine-grained structures have been produced, and their weldability has been investigated. 8,9) In order to broaden the application of Mg alloys in transportation industries, the joining of Mg alloys to aluminum (Al) alloys becomes important and necessary. In the dissimilar joint of Mg and Al alloys, intermetallic compound (IMC) is always generated.…”

Microstructural characteristics and mechanical properties of non-combustive Mg–9Al–Zn–Ca magnesium alloy friction stir welded joints

“…In recent years, FSW of high melting temperature materials such as steels, nickel and Ti alloys has become a research hotspot [16][17][18]. Though FSW of conventional magnesium alloys has been intensively investigated, especially for the MgAl-Zn (AZ) series [19][20][21][22][23], few studies dedicated to non-combustive magnesium alloys have been reported [24][25][26][27]. Zhang et al [24] studied microstructural evolution of the non-combustive Mg-6%Al-3%Ca-0.5%R.E.-0.2%Mn magnesium alloy due to friction stir welding.…”

“…Zhang et al [24] studied microstructural evolution of the non-combustive Mg-6%Al-3%Ca-0.5%R.E.-0.2%Mn magnesium alloy due to friction stir welding. Yamamoto et al [25] and Chen et al [26] conducted friction stir spot welding and friction stir welding of non-combustive Mg-6%Al-0.5%Mn-2% Ca (AMX602) magnesium alloy, respectively. Choi et al [27] made microstructure evaluation of friction stir welded AZ91 with CaO non-combustive Mg Alloy.…”
