Effects of the Interaction Length between Hollow Shapes: Application to a HCP Metal under Mechanical Loading

Résumé

The mechanical response of a hexagonal closed-packed (HCP) metal is analyzed in this study using perforated parallelepiped specimens deformed with a compression device at room temperature in order to generate plastic deformations. Each specimen contains two parallel hollow cylinders for which a characteristic distance d is defined. This length corresponds to the initial length between the two cylinders. Four values of d are considered in the study for specimens cut from a commercially-available pure titanium sheet : d = 1 mm, 2 mm, 3 mm and 4 mm. Different experimental characterizations are carried out thanks to the mechanical tests. The experimental force-displacement curves indicate significant level differences for the considered values of d. After the mechanical tests, the geometry of the specimens is analyzed and the microstructures in the vicinities of the new hollow shapes are investigated notably in central, peripheral and upper zones. Different experimental techniques are used for the characterization of the specimens particularly after the mechanical tests, among them electron backscattered diffraction (EBSD).
