Semisolid casting with ultrasonically melt-treated billets of Al-7mass%Si alloys

For the Al-Si5Cu3 alloy the results obtained in this work confirm that cooling rates influence the nucleation and growth of α c -Al 15 (Fe,Mn) 3 Si 2 and β- Al 5 FeSi phases.

The effect of solidification processing parameters ( Sp and Ṫ ) and Si content on the secondary dendritic arm spacing (λ 2 ) and resulting hardness in hypoeutectic Al-Si alloys

We proceed as follows: In the next section (2.), we will bring together some of the key arguments from the EU ’s democratic deficit-debate, hinted at above, and the literature

These proteins were also recognized by cells from a significant proportion of the household contacts of multibacillary leprosy patients, but in contrast, few responses were observed

The efects of heat-treatment on the microstructure and phase transformations of Cu-25%Zn-4%Al and Cu-30%Zn- 4%Al alloys were investigated in this work. The alloys were prepared

For the Al-Si5Cu3 alloy the results obtained in this work conirm that cooling rates inluence the nucleation and growth of α c -Al 15 (Fe,Mn) 3 Si 2 and β- Al 5 FeSi phases.

4, is observed at about 380 ºC in Cu-Al alloys [2], indicating that the increase in the Al concentration and the presence of Ag are decreasing the β 1 phase decomposition reaction

corrosion behaviour of Al alloys covered with Ce conversion coatings, however, it seems that the results obtained by these authors are more linked to the thickening of the Al
