Narrow Results

TFDC (Thomas-Fermi-Dirac-Cheng) electron theory is applied to analyzing the characteristics of the electrons inside the double layer of the nanometer composite thin films. This paper proposes the new mechanism about the high capacity in both theoretical analysis and experimental measurement.

Mechanical alloying (MA) has been utilized to synthesize many equilibrium and/or nonequilibrium phases. During the MA process, alloys are formed by the solid-state reaction. Solid solution has been obtained by MA, strain occurs due to the dissolution one component in the binary system. An understanding of the strain in mechanical alloyed Ti–Al, Fe–Al, Ni–Al from the electronic level has remained elusive. In this communication, atomic strain behavior of Ti–Al, Fe–Al, Ni–Al systems is analyzed on the basis of the TFDC (abbreviation of the name of Thomas, Fermi, Dirac, and Cheng) electron theory. Lattice strain of Ti, Fe, Ni, and Al are compared with available experimental results. A very good coincidence was found.
