Abstract
The solution heat treatment of Mg-Tb and Mg-Tb-Nd alloys with relatively high solute concentration was characterized by electrical resistivity measurements at 77 K and 293 K. Linear concentration dependence of resistivity at 77 K and 293 K was observed for solution treated Mg-Tb alloy. The resistivity contributions of 1 at.% of Tb in magnesium at 77 K and 293 K were determined. Negative deviations from Matthiesen’s rule were found in solution treated Mg-Tb and Mg-Tb-Nd alloys. Precipitation of the D019 phase in solution treated Mg-Tb alloy decreases the slope of resistivity-concentration dependence but does not change the sign of deviation from Matthiesen’s rule.

Key words
Mg alloys, rare earth, terbium, electrical resistivity
