Influence de l’epaisseur sur le coefficient de dilatation thermique de la tole almgsi

الملخص EN

The purpose of this paper is the study of the effect of the thickness on the thermal expansion coefficient of the AlMgSi sheet.

The results obtained are highly dependent on the thickness.

The dilatometric curves vary from one direction to another.

There is the presence of an anisotropy whose intensity depends on the thickness and the measurement direction.

The measurements of the thermal expansion coefficient, of the sample whose thickness 1.15mm, taken along the Y direction is lower than those of the others.

This behavior makes it interesting in the industrial field.
