Difúze 71Ge a 68Ge v Mg a ve slitině Mg-2Al
Čermák, Jiří ; Eversheim, D. ; Rothová, Věra ; Stloukal, Ivo
Measurement of Ge diffusion coefficients in Mg and in Mg-1.8 wt.% Al alloy is presented in this work. Two techniques of Ge deposition and two annealing atmospheres (Ar and Ar + Cl2) were tested which might reveal possible influence of hold-up effect at the free surface on the diffusion behavior. The present results are compared with the literature data for volume diffusion of other impurities in Mg.
Heterodifúze In-114m ve slitinách na bázi Mg-Al
Čermák, Jiří ; Rothová, Věra ; Eversheim, D. ; Stloukal, Ivo
Diffusion of radiotracer In-114m implanted in Mg-2Al solid solution, Mg-33Al eutectic alloy and Mg17Al12 intermetallic was studied by both residual activity and serial sectioning methods in the temperature interval 175 ? 575 °C. The differences in In diffusivity was discussed in terms of chemical composition.
