Impurity and temperature dependence of the electrical resistivity of dilute alloys of aluminum

Theory and experiment on deviations of Matthiessen's rule in dislocated crystals: a constructive reply

“…Concerning point (i), only a few experiments exist (parallel observations by electrical resistivity arid by TEM, [11][12][13]). Several investigations, however, were made with respect to (ii), DMRS in connection with dislocations as a function of measuring temperature, although there emerged marked differences in the nature and extent of DMRS observed [14-191. Furthermore, there has been reported a series of theories [20][21][22] which predict such distinct DMRS in case of coexisting isotropic and anisotropic scatterers, the most extensive having been formulated by Kaveh and Wiser [22,23]. Here, satisfactory agreement with related experiments could be gained for the case of cooperative impurity and phonon scattering [22].…”

Accelerated recrystallization by electric current flash heating in cold-rolled Al-5Cu alloy under the influence of concurrent precipitation

“…After the current reaches the desired value, the heating rate gradually increases with time until a maximum of 142 °C/s is achieved. In addition to the non-perfect square shaped current profiles, this heating rate variation during heating should also be attributed to the electric resistivity of the samples which is temperature and solid solution level dependent [23][24][25]. In the end of heating cycle, the heating rate sharply drops to a minus value before the current reduces to zero.…”

Negative deviations from Matthiessen's rule for SrRuO 3 and CaRuO 3

“…The effect of a non-spherical Fermi surface has been calculated, for instance, for aluminium [17]. Using the correct transport factor, which turns out to be of order unity, accounts for the observed low-temperature T 3 -dependence for ρ(T ), rather than the usual T 5 -dependence.…”
