Abstract

L'invention concerne un corps comportant au moins une matière de faible résistance mécanique, en particulier une vitrocéramique, un verre ou une céramique et une matière métallique. L'invention est caractérisée en ce que la matière de faible résistance mécanique forme avec la matière métallique une liaison de matière qui est résistante aux hautes températures, pour des températures supérieures à 250°C , en particulier supérieures à 300°C, de préférence supérieures à 400°C, en particulier supérieures à 500°C, et la liaison de la matière à faible résistance mécanique et de la matière métallique comprend une couche intermédiaire entre la matière à faible résistance mécanique et la matière métallique et la couche intermédiaire est constituée d'une matière ductile, de préférence un métal ductile, en particulier un matière ductile, de préférence un métal ductile, ayant une élongation à la rupture ≥ 1%, de préférence ≥ 2%, en particulier ≥ 4%, tout particulièrement ≥ 10%, en particulier dans la gamme de 1% à 20%, de façon tout particulièrement préférée dans la gamme de 2% à 15%.
