Effect of TiC Particles Volume Fraction on the Mutual Diffusion of Al and Mg during Fabrication of Al-4.5wt%Mg/TiC via Mechanical Alloying Process O.
Peak position (Al(111)), broadening value, microstrain and crystallite size of samples.
Therefore, increasing the TiC particles led to increasing the mutual diffusion of Al and Mg.

Two different types of substitution were considered: (1) Al substitutes for Ti, and (2) Al substitutes for N.
In order to conclude which sites may be occupied by small amount of Al in TiN with NaCl structure one of Ti or N atoms in the expanded cubic supercell was substituted by Al.
The obtained energies allow us to determine the site occupied by Al atoms in Ti-Al-N.

In this analysis, δ for the solutes Al, V, and Fe was calculated from the respective 12-coordinate metallic radii and δ for the interstitial O was estimated from the volumetric change associated with O additions [5].
Foltz et al also observed that slip was readily transmitted into the beta phase given a Burger’s orientation relationship between the alpha and beta phases [13].

Clark et al. [1] first presented a SMA-based damper, which consists of two groups of parallel pre-tensioned SMA wires.
Dolce et al. [2] improved this damper by adding another group of SMA wires, functioning as re-centring group.
Robert et al. [3] presented an important class of SMA damper - the center- tapped (CT) device, which is studied the most currently.
It is noteworthy that damping effect of maximum story drift of M3 under El Centro (NS) wave is smaller than that of M1
