Zener relaxation strength in b.c.c. and f.c.c. alloys
Welch and Le Claire's theory (Philos. Mag., 16 (1967) 981) is extended to include the relaxation strength of the Young and bulk moduli. A complete set of equations is given for the calculation of the relaxation strength of all the moduli in both f.c.c. and b.c.c. alloys. The relaxation strength...

| Sumario: | Welch and Le Claire's theory (Philos. Mag., 16 (1967) 981) is extended to include the relaxation strength of the Young and bulk moduli. A complete set of equations is given for the calculation of the relaxation strength of all the moduli in both f.c.c. and b.c.c. alloys. The relaxation strength of the Young modulus in β-brass and Cu3Au is discussed in terms of these equations. Some ordering parameters are obtained from the anelastic data, which are confirmed by independent estimates. © 1994. |
