Experimental Procedure The 6082-Al alloy has the following composition in weight % as: 0.99 Mg, 1.46 Si, 0.58 Mn, 0.36 Fe, and the rest is Al.
This behavior is similar to that observed in a number of powder metallurgy Al alloys and Al metal-matrix composites [7, 8].

Fig. 2 a) Schematic of layer arrangement, b) Schematic band diagram of EL diode under forward bias V (Φ1 and Φ2, work functions of ITO and Al, respectively).
The work functions for Al and ITO are 4.3 and 4.6 eV, respectively.
The EL spectra of these devices were calculated as a function of layer thicknesses.

Crystals on the COL fibers were aligned closely to the perimeter of the fibers )1( COL EL FN-EL FN and their size after 12 hours of exposure was comparable to crystals grown on the FN-EL fibers after 48 hours of exposure.
EL can not template the big crystal after 48 hours although the relative modulus of EL fibers increased in the early stage of mineralization.

ECAP of the extruded Mg-Al-Ca alloy further increased strength and ductility, especially after aging (YS = 190 MPa, EL = 12%).
Mechanical properties (a-YS; b-EL) of Mg-0.49%Al-0.47%Ca alloy at Ttesting = 20 o C and 160 oC (shaded) after different treatments: 1 - annealing; 2 - quenching; 3 - annealing + ECAP at 300 o C; 4 - quenching + ECAP at 300 o C; 5 - extrusion + ECAP at 300 o C.
