The effect of Zr on dynamic recrystallization during ECAP processing of Mg-Y-RE alloys

Characterization of microstructure and texture of binary Mg-Ce alloy processed by equal channel angular pressing

“…Similar texture formation has been described in LAE442 (Mg-4Li-3.5Al-1.3Ce, wt.%) and WN43 (Mg-4Y-3Nd, wt.%) alloys processed by ECAP up to 8 passes using route Bc [6,12].…”

“…Accordingly, the origin of the formation of the P-fiber and <0001> // TD components was explained by the massive activation of the <c+a> pyramidal and prismatic slip systems, respectively [6,12]. However, it is well known that the activation of <c+a> pyramidal slip system needs more energy than the prismatic slip and hence the prismatic slip system is expected to be activated before the <c+a> pyramidal slip.…”

“…Over the last decades, grain refinement and texture modification through applying thermomechanical processing or alloying addition elements are considered the crucial features for improving the mechanical properties of Mg-based alloys [3][4][5][6][7][8][9][10][11][12].…”

“…Severe plastic deformation (SPD) techniques such as equal channel angular pressing (ECAP) have proven their efficiency in producing ultrafine-grained microstructure down to the sub-micrometer level in several Mg-based alloys [3,5,11,12]. Despite the high stacking fault energy (γSFE = 125 mJ/m 2 ) of Mg, dynamic recrystallization (DRX) is the main mechanism for grain refinement in Mg-based alloys due to the limited number of slip systems [13].…”

Influence of Texture on the Mechanical Properties of a Mg-6Al-1Zn-0.9Sn Alloy Processed by ECAP

“…The advantages of their high specific strength give magnesium (Mg) alloys wide prospects for lightweight applications in the aerospace, automotive, and electronic fields [1,2]. However, the low formability and strong plastic anisotropy of Mg alloys limit the development of their wider industrial applications [3,4]. Now, some new types of Mg alloys have been developed based on the common Mg-Al-Zn system, which is by adding extra rare earth elements [5,6].…”
