| Summary: | In the frame of this investigation, the homogeneity of six (6) ingots of
aluminum alloy EN AW-5083 cast by semi-continuous vertical Direct Chill
casting (DC) Process was investigated correlating mechanical properties in
as-cast and homogenized condition. The investigation followed the static
design of the Latin square. Determination of the ultimate tensile strength
and elongation across the cross-sectioned sliced at the ingots’ fronts and
rears in as-cast state revealed differences per cross section of each
particular slice. Comparison of obtained differences enabled evaluation of
mechanical properties homogeneity of the ingots as a whole. The influence and
significance of homogenization was also quantified correlating the mechanical
properties results for as-cast and homogenized state at the front and rear
position in ingot. The results were processed using the StatSoft® STATISTICA
13.2 software package using charge, slice height and slice width as sources
of variability. Comparison of obtained statistical results for both states
respectively in respect to the sampling position enabled estimation of
homogenization process influence on mechanical properties. |
