The thermal conductivity has been measured of a series of copper-zinc alloys in the range 4.2-1.1掳K and the lattice part of the conductivity was determined. The value obtained for K ge is 1.1 脳 10 3 T 2 W/cm-deg, which is compared with the lattice thermal conductivity that can be ...
The thermal conductivity and electric resistivity of two pure copper materials and nine commercial copper alloys were measured in the approximate range 1300-1500 K. The thermal conductivity was measured by the guarded axial-rod longitudinal-heat-flow technique. The samples were contained in thin-...
The present paper contains the results of thermal conductivity measurements of the alloys of this system in the region of solid solutions alloyed with copper telluride over a wide temperature range from 300 to 1000 °K, as well as the analysis of the data obtained. To this end, alloys were ...
1 Heat capacity and thermal conductivity of copper Our investigations into the properties of an ideal gas lead to the conclusion that the internal energy is proportional to the temperature, and that therefore the specific heat is constant, ( ) 2 vc f nR = . The thermal conductivity of an id...
Validity of Wiedemann-Franz-Lorenz Law leads to the knowledge of thermal conductivity indirectly by the electrical conductivity measurements. Studies on copper-manganese alloy system carried out indicated the non-availability of Wiedemann-Franz-Lorenz Law. High specific resistance of these alloys coupled ...
thermal conductivityThe effect of the addition of n-layer graphene on the thermal conductivity of copper samples sintered at high pressure and temperature was studied. It was shown that the addition of graphene Gn (4) to copper powder in an amount of 0.2–0.4 wt % allows an increase in the...
Experimental data are reported for the lattice component ( k g) of thermal conductivity observed in a large number of copper-rich and silver-rich alloys. At temperatures T ≤θ >D 30 where it is observed that k g = BT 2, the values of B for well-annealed alloys are found to decrease...

Heat conductivity is the ability of a body to transfer energy in the form of heat in a non-uniformly heated solid (without thermal radiation). From: Fundamentals of Evaluation and Diagnostics of Welded Structures, 2012 About this pageAdd to MendeleySet alert ...
Results are presented on the isochronal annealing recovery of the 1-4K lattice thermal conductivity of a deformed Cu + 7 atomic % Ge polycrystal. The theory of the modification of dislocation thermal resistivity by solute atmospheres, due to Klemens and Ackerman, predicts a gradual recovery of the...
