Etude dilatometrique d’une tole almgsi ayant differentes epaisseurs

الملخص EN

The purpose of this paper is to study the influence of the thickness of a sheet, of an Al-Mg-Si alloy, on the thermal expansion coefficient.

This sheet contains other alloying elements.

Three samples were taken along the parallel direction, the perpendicular direction to the rolling direction in the rolling plan and the perpendicular direction to the rolling plan (Z direction).

The obtained results show that the dilatometric behaviour changes strongly with thickness.

It is important to notify that the obtained thermal expansion coefficient along Z direction of the sheet whose thickness is about 1.35mm is very low compared to that of the two other sheets with 1mm and 1.15mm as thickness.
