Effect of neodymium, gadolinium addition on microstructure and mechanical properties of AZ80 magnesium alloy

The Role of Sm in Precipitates, Grain Sizes,and Tensile Properties of As‐Cast and As‐Extruded AZ31–0.3La Alloys

“…Magnesium alloys with high strengths and toughness could be acquired by heavy alloying of heavy rare-earth elements at present; however, it could lead to high costs of materials, which could further increase the difficulties of their popularizations and applications in civil transportations. [7][8][9] In recent years, adding light rare-earth elements to refine the microstructures and enhance the properties has been attracted more and more attentions in magnesium alloys, which has the same effect of the heavy rare-earth elements, such as Gd and Y. [10][11][12][13] As the relatively cheap light rare-earth element, La or Sm has been reported to be effective for improving the properties of magnesium alloys.…”

“…As a result, their applications as the main load‐bearing structural materials and heat‐resistant structural materials are limited. Magnesium alloys with high strengths and toughness could be acquired by heavy alloying of heavy rare‐earth elements at present; however, it could lead to high costs of materials, which could further increase the difficulties of their popularizations and applications in civil transportations …”

Experimental and DFT studies of gadolinium decorated graphene oxide materials for their redox properties and as a corrosion inhibition barrier layer on Mg AZ13 alloy in a 3.5% NaCl environment

“…7 OCP studies of epoxy and Gd decorated GO coated Mg alloys. thus showing the composite material having excellent physisorption on the alloy surface, [43][44][45] as shown in Fig. 9C.…”

“…S3a † shows local degradation caused by corrosive ion reaction with the epoxy coating, indicating that epoxy coating cannot protect the alloy for a long time in a corrosive medium and circles demonstrate the localised attack on the alloy surface, and the arrow indicates the formation of pinhole by the attack of corrosive ion. [45][46][47][48] Fig. S3b † shows the depth of local degradation on the Mg alloy, and dotted line circles represent the attack of corrosive ion on the surface.…”

Effect of Solution Treatment on Microstructure and Corrosion Properties of Mg–4Gd–1Y–1Zn–0.5Ca–1Zr Alloy

“…For instance, Mg-Al-Zn series alloys were a category of widely used commercial Mg alloys, and the mechanical properties of these Mg alloys were enhanced by the methods of hot extrusion, severe plastic deformation and so on [16][17][18][19][20]. Nevertheless, the appropriate addition of alloying elements, especially rare earth (RE) elements, has become a hot topic for their more direct and beneficial effects on the microstructure evolution and comprehensive property improvements of Mg alloys [21][22][23][24][25]. Recent studies have revealed that Mg alloys with RE additions showed refined grain size and novel phases, which were beneficial to the strengths of Mg alloys.…”
