Resistivity temperature – dependence and residual resistivity concentration-dependence in pure noble metals(Cu, Ag, Au) have been studied at low temperatures. Dominations of electron – dislocation and impurity, electron-electron, and electron-phonon scattering were analyzed, contribution of these mechanisms to resistivity were discussed, taking into consideration existing theoretical models and available experimental data, where some new results and ideas were investigated.

Precise measurements of the electrical resistivity of pure copper samples have disclosed two discontinuities in the temperature dependence of the resistivity. They occur at approximately 6.7 K and near 12.1 K. The second is associated with impurity effects whereas the first appears to be a characteristic of the metal itself. It is similar to the discontinuity previously observed in the temperature dependence of the electrical resistivity of Ag by Kos and independently by Ehrlich and Schriempf and attributed by the former to one-step umklapp processes.

The thermal expansion, the electrical resistivity and the specific heat of Mn-rich bcc Cr-Mn alloys have been measured. Distinct negative temperature dependence was observed in the thermal expansion and the resistivity at low temperatures. These anomalies are successfully explained on the basis of the two electronic state model by taking account of a local environment effect. An enhanced specific heat at low temperatures is consistently understood in terms of the proposed model.

AbstractW360 is a hot work tool steel produced by voestalpine BÖHLER Edelstahl GmbH & Co KG, a special steel producer located in Styria, Austria. Surface tension and density of liquid W360 were studied as a function of temperature in a non-contact, containerless fashion using the oscillating drop method inside an electromagnetic levitation setup. For both, surface tension and density, a linear model was adapted to present the temperature dependence of these measures, including values for the uncertainties of the fit parameters found. The data obtained are compared to pure iron (with 91 wt% the main component of W360), showing an overlap for the liquid density while there is a significant difference in surface tension (− 5.8 % at the melting temperature of pure iron of 1811 K).
