Effect of Ce addition on the microstructure and tensile properties of extruded Mg–Zn–Zr alloys

Enhanced Electromagnetic Interference Shielding of Mg–Zn–Zr Alloy by Ce Addition

“…Analysis of selected-area electron diffraction of Mg-Zn-Ce particle (as shown in Fig. 5c) indicated that the Mg-Zn-Ce phase was a orthorhombic structure, which was consistent with the report by Jeong et al [17]. The Mg-Zn-Ce phase has the similar composition to (MgZn) 12 Ce phase reported by Kevorkov and Pekguleryuz [15].…”

Effect of Y and Ce additions on microstructure and mechanical properties of Mg–Zn–Zr alloys

“…6 (a). The particle was identified as the Mg-Zn-Ce phase, with its special orthorhombic structure as reported in the literatures [12,19]. The bright field TEM image of Mg 3 Zn 3 Y 2 is indicated by an arrow in Fig.…”

Microstructure, texture, mechanical properties and electromagnetic shielding effectiveness of Mg–Zn–Zr–Ce alloys

“…An early study reported that Mg-Zn-Zr alloys, typically ZK60, exhibit high strength, excellent deformability and low cost, and can thus be modified with the addition of other elements, such as rare earth of Ce, Y, Gd and alkaline earth element of Ca, to yield the expected mechanical properties [7,8]. Ce addition plays an important role in obvious grain refinement, developed texture and mechanical properties of Mg alloys [9][10][11][12]. To date, several investigators have reported the effect of Ce addition on the microstructure and performance of Mg-Zn-Zr alloys.…”

“…Yu [12] pointed out the dynamic recrystallization promoted by particle nucleation at the Mg-Zn-Ce phase, which reduced grain size and weakened the basal fibre texture. Jeong [10] reported that the addition of Ce to Mg-Zn-Zr alloy resulted in a change in the type of second phase particles from MgZn to Ce(Mg 1 À x Zn x ) 11 . Sabat [13] found the deciding role of texture on ductility in a Ce-containing Mg alloy.…”
