[5] Annealing Study of Al-Mg Wrought Alloys using Two

Activation Enthalpy of Migrating Defects

Aly and Emad A.Badawia Faculty of Science, Physics Department, Minia University, Egypt aemadbadawi@yahoo.com Keywords: Activation Enthalpy of Migration, Al-Mg Wrought Alloys, Electrical Resistivity, Hardness, Isothermal Annealing Abstract The electrical resistivity and the corresponding mechanical properties (hardness) of some 5xxx Al-Mg alloy processed by plastic deformation were investigated.
Experimentally the situation is not simple as well: the elastic stored energy is low (a few tenths of J/g in Al), even for high strains, making its measurement difficult.

Referring to Table 1, it is observed that with increase in test temperature, approximately, 50% drop on % EL at 700° C, but 30 % reduction in % RA compared to that of at RT.
There is not much reduction in % EL & % RA when tested at 400 °C.

A triangular wave form of frequency 0.33Hz was used during LCF test as per Hales R et al [6].
According to Moris et al [8], Bauschinger ratio ‘φ’ has been computed using Eq. (2) which is expressed as (2) where, σt - Tensile stress at Half life σc - Compressive stress Half life σy - Yield stress A material is said to be isotropically hardening when φ=0 while kinematically hardening when φ >1 [10].

For the calculation of thermal conductivity of solids are the most important two contributions: the heat transport by electrons (el) and by phonons (ph).
(2) Thus the partition function Z is a product of terms of the ground state (0), the translation (trans), the vibration (vib), the rotation (rot), the internal rotation (ir), the influence of electrons excitation (el), the influence of nuclei excitation (nuc) and the influence of the intermolecular potential energy (conf).
Comparisons with the computer simulation data indicate that the expressions developed yield better results (pressure, internal energy, free energy) than theory of Weeks at al. [7-9], Barker and Henderson [7-9].
