Abstract

L’invention concerne une éprouvette (10) pour la mesure de contraintes résiduelles engendrées dans une pièce lors d’un procédé de fabrication additive de la pièce par fusion laser sur lits de poudre, ladite éprouvette étant formée par fabrication additive par fusion laser sur lits de poudre identique à celle utilisée pour la pièce à fabriquer, caractérisée en ce que ladite éprouvette est de forme générale cylindrique et présente des premier et deuxième plans de symétrie orthogonaux entre eux et à une base du cylindre (12), en ce que ladite éprouvette est extrudée sur une partie de la hauteur du cylindre à partir d’une première extrémité (18) du cylindre en direction d’une deuxième extrémité (16) du cylindre, et en ce que ladite éprouvette présente marquage à ladite première extrémité du cylindre, ledit marquage s’étendant selon l’un des premier ou deuxième plans de symétrie. Figure pour l'abrégé : Figure 3The invention relates to a specimen (10) for measuring residual stresses generated in a part during an additive manufacturing process of the part by laser fusion on powder beds, said specimen being formed by additive manufacturing by laser fusion on beds. of powder identical to that used for the part to be manufactured, characterized in that said test piece is generally cylindrical in shape and has first and second planes of symmetry orthogonal to each other and to a base of the cylinder (12), in that said test piece is extruded over a part of the height of the cylinder from a first end (18) of the cylinder towards a second end (16) of the cylinder, and in that said specimen has a marking at said first end of the cylinder, said marking extending along one of the first or second planes of symmetry.
