Recent developments and applications on high-performance cast magnesium rare-earth alloys

Advances in coatings on magnesium alloys for cardiovascular stents – A review

“…cerium (Ce) [ 49 ], neodymium (Nd) [ 50 , 51 ], and yttrium (Y)) [ 52 , 53 ], and zirconium (Zr) [ 54 , 55 ], etc. [ 56 ]), to pure Mg, to render the metal (under certain process conditions) become an alloy with expected performance. Moreover, the alloying design has an important effect on the strength, plasticity, and corrosion resistance of Mg ( Fig.…”

The effect of co-addition of La and Nd on microstructures and mechanical properties of squeeze-cast Mg-Al-Zn-La-Nd alloys

“…Adding REs reduces the content of Mg 17 Al 12 in the alloy, which may slightly reduce the hardness and strength of the alloy. However, the formed Al x RE y (Al 11 RE 3 and Al 2 RE) can effectively improve the hardness and strength of the alloy, especially the high-temperature mechanical properties [27].…”

The Corrosion Behavior of As-cast Mg–4Al–<i>x</i>Er–0.3Mn Alloys

“…13 According to the previous studies, adding RE elements to the alloy can form the more stable passivation film on the surface. [1][2][3][4][5][6][7][8][9][10][11][12] However, there are very few reports about Er effect on the corrosion behavior in Mg-Al system alloys (to the knowledge of the authors). Therefore, in this paper the corrosion behavior of the Mg-4Al-xEr-0.3Mn alloys (denoted as AE4x, E represents rare earth element Er, x = 2, 4 and 6) was analyzed and the corrosion mechanism was revealed.…”

“…

Magnesium and magnesium alloys are light-weighting candidates as the structure materials. The microstructure and corrosion behavior of 4,6 all in wt%) alloys were studied. The results showed that the morphology, size and distribution of Mg 17 Al 12 phase were gradually improved with the increasing of Er content, and a large number of Al 2 Er were observed.
