The Coefficient of Thermal Expansion of Various Cubic Metals Below 100 °k

Abstract: Measurements have been made of the coefficient of linear thermal expansion, α, of Cu, Ag, Au, Al, α-Fe, and Ni at temperatures below 100 °K using an interferometric method in which the spacer between the optical flats of a Fabry–Perot-type interferometer was made of the material studied. The lowest temperatures at which values of α are given are about 20 °K (Cu, Ag), 11 °K (Au), 25 °K (Al, Fe), and 32 °K (Ni). The results are discussed in terms of the Gruneisen parameter γ which, for Cu, Ag, and Au, is approxi… Show more

“…The constraint that interdependent equations 1 and 2 simultaneously fit the experimental determinations of a(T) and α(T) from 0K to near the melting point of 933K resulted in the large number of terms in both functions to ensure excellent simultaneous fits spanning the whole temperature range where aluminium is a solid. Previous efforts to fit functions to both a(T) and α(T) were based largely on polynomials and were only valid over limited temperature ranges (59,63,68,70,77,91,95,96). One particular example by Kroeger and Swenson (96), which represents some of the most rigorous work to date for α(T), fits numerous polynomial functions of varying order to four separate temperature ranges that in combination go from 0K to 330K.…”

“…The first system, pure copper (Cu) 27,28 , possesses cubic symmetry and therefore a) Electronic mail: Nicholas.pike@smn.uio.no the CTE is a single temperature-dependent value. The temperature dependent properties of copper are thoroughly investigated experimentally 27,[29][30][31][32][33][34][35][36][37] and Cu is consequently used to determine the quality of our calculation methods. The second material, aluminum nitride (AlN) 38 , has a hexagonal crystal structure and therefore two unique non-zero CTE's and is used to demonstrate our ability to calculate the expansion coefficients of an anisotropic material with a known temperature dependent anharmonic interaction 18 .…”
