The ability of Al-Si alloys to be cast into complex shapes, coupled with a favourable strength-to-weight ratio, has given them an advantage in the automotive industry.
Simultaneously, the alloy maintains a favourable level of %El from HT1 to HT7.
The decrease in %El is sharp from HT1 to HT2, and gradual from HT2 to HT7.
Tensile sample (HT7, %El. = 14.5%) with a fully globular microstructure.

The correlations can be expressed: UTS=410.4-0.8SDAS and El%=7.9-0.05SDAS.
The correlations between UTS, El and SDAS can be expressed to be linear: UTS=410.4-0.8SDAS and El=7.9-0.05SDAS.

This will in turn induce a partial recovery of the Vf drift, as was reported by Caldwell et al. [7, 17].
Green EL of C-Core PDs.
However, by using EL spectrallyselective imaging, the spectra of the EL emission from an individual extended defect can be discerned.
Galekas et al, [19] reported a spatiallydiffuse, 510 nm (2.43 eV) emission that dominated the EL spectra and was attributed to a 'presumably boron-related' point defect.
Bockstecite et al. [24] demonstrated that boron interstitials can form stable complexes at carbon sites, creating deep-level acceptor states that are consistent with such EL emission.

Sun et al., [9] found that small amount of Al addition enabled single-phase Ti3SiC2 synthesis and the optimal sintering temperature for the Ti3SiC2 synthesis is greatly decreased by the Al addition.
However, when more Al was added (x=0.3), the purity of Ti3SiC2 began to decrease and wt. % of TiC and Ti5Si3 started to increase in XRD analysis, suggesting that excessive Al would lower the Ti3SiC2 purity as reported by Jin et al., [10] in their study on the effect of Al addition on phase purity of Ti3Si(Al)C2 synthesized by mechanical alloying.
In fact this phenomenon had been stated and explained by the mechanism proposed by El-Raghy and Barsoum [1], in which during the last stage of the sintering process, Ti3SiC2 may continue to react with C to form TiC.

Experimental methods An AZX311 alloy extrusion sheet with an initial thickness of 3 mm and chemical composition of 3.5% Al, 0.88% Zn, 1.32% Ca, 0.35% Mn, 0.006% Si, 0.001% Cu, <0.001% Ni, <0.001% Fe, and bal.
Results of the tensile yield strength test, the Y.S., U.T.S., and El., are also shown.
Annealing at a temperature of 423 K slightly decreased the Y.S. and U.T.S. values, but El. increased to 10% from the 5% El. of the as-rolled alloy.
After annealing for 100 h, the Y.S. and El. were 300 MPa and 7%, respectively.

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.

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].
