Influence of deformation on precipitation process in Mg–15wt.%Gd alloy

Microstructure and Mechanical Properties of Ultra-Fine Grained Az31 Alloy Processed by Ecap

“…Further ECAP processing (N>2) causes a gradual decrease of I 2 . Note that we have observed similar dependence of the intensity of dislocation component on strain (number of passes) also in other Mg alloys (AZ80, ZK60) [15]. …”

Effect of Zr, Mn and Sc additions on the grain size of Mg–Gd alloy

“…Previous work shows that the rare earth element Gd could improve the high-temperature behavior of Mg alloys remarkably. Mg-Gd alloys with the content of Gd more than 10 wt.% exhibit good mechanical properties and high creep resistance comparable to or better than those of commercial WE type alloy [2][3][4][5].…”

Positron annihilation lifetime spectroscopy study of roller burnished magnesium alloy

“…There are two ways of explaining the lack of ) [11] or, in contrast, all positrons are trapped in defects. The lifetime expected for the Mg bulk value was found to be between 218 ps and 225 ps [10,[15][16][17][18]. Thus, the lifetime observed in the AZ91HP alloy would rather point to the fi rst explanation.…”

“…A single component spectrum is often observed in untreated Mg-rich alloys, but usually its lifetime is closer to 225 ps [8,[10][11][12][13]. However, a lifetime of 220 ps was also reported [14].…”
