“…The chemical compositions of all phases were in good agreement with those determined previously (Table 1). 9,13,18) Figure 2 shows SEM images of AE samples, revealing that extrusion-induced microstructure deformation and recrystallization were observed for both alloys. Moreover, the fractions of 14 H (0.13 vol%) and lamellar (1.55 vol%) LPSO phases decreased in as-extruded GZ101, with as-extruded GZ101-1Zr containing 0.51 vol% of the lamellar LPSO phase.…”

“…9,11) However, the optimization of Zr content in Mg-RE alloys is still underexplored. 12,13) Herein, we describe how the corrosion resistance of Mg alloys can be improved by Zr addition and extrusion, by subjecting extruded samples placed in 3.5 mass% aqueous NaCl to electrochemical corrosion and immersion tests and further probing their properties by eld emission scanning electron microscopy (FE-SEM) coupled with energy-dispersive X-ray scatter (EDS) and electron backscatter diffraction (EBSD) analyses.…”

Effect of Zr Addition on the Corrosion Behavior of Extruded Mg Alloys in NaCl Solution

The effect of Zr addition on the corrosion behavior of an extruded Mg-10Gd-1Zn alloy (GZ101) in 3.5 mass% NaCl solution was investigated by electrochemical and immersion tests in 3.5% NaCl solution. The addition of 1 mass% Zr to GZ101 (to afford GZ101-1Zr) decreased the fraction of 14H (number of stacking layers and H-Hexahedral structure) and lamellar long period stacking ordered (LPSO) phases across the α-Mg matrix and increased the fraction of the X-phase (Mg 12 GdZn) formed at grain boundaries. Extruded GZ101-1Zr exhibited a signi cantly smaller corrosion rate than extruded GZ101 (0.13 vs. 2.11 mm year −1 ) due to containing less 14H/lamellar LPSO phases (detrimental to corrosion resistance) and featuring a noble {1010} prismatic texture in the extrusion direction.

“…Previous works [1,[6][7][8] had shown that the mechanical properties and creep resistance of Mg-Al serial alloys can be improved by the addition of Ca, Sr, Ti, Zr and RE. As a lower-cost and lower-density (1.55 g/cm 3 ) element, Ca can significantly improve the creep resistance and high-temperature mechanical properties of Mg-Al alloys through forming stable eutectic phase [9,10].…”

In this work, the Mg-5Al-2Ca alloy was extruded at 573, 623 and 673 K, with a ratio of 16:1 and a constant speed of 3 mm/s. Results demonstrate that the Al 2 Ca particle is formed in Mg-5Al-2Ca alloy. The size, amount and distribution of Al 2 Ca particles are influenced evidently by extrusion temperature. Unlike previous reports, the intensity of basal texture increases with increasing extrusion temperature, and the reasons are analyzed and given. Even though the average grain size increases as the extrusion temperature increased from 573 to 623 K, the YS, UTS and elongation of asextruded Mg-5Al-2Ca alloy are almost kept the same at 573 and 623 K. The reason is speculated as the balance of grain size, Al 2 Ca phase and texture at the two temperatures. The work hardening rate depends on extrusion temperature, and the largest h value of Mg-5Al-2Ca alloy is obtained when the extrusion was performed at 623 K.
