Title (EN) SUPERHARD CONSTRUCTIONS & METHODS OF MAKING SAME
(FR) CONSTRUCTIONS SUPER-DURES ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) A super hard polycrystalline construction is disclosed as comprising a body of super hard material having a first fraction of super hard grains in a matrix of a second fraction of super hard grains. The average grain size of the first fraction is between around 1.5 to around 10 times the average grain size of the second fraction and the first fraction comprises around 5 vol% to around 30 vol% of the grains of super hard material in the body.
(FR) L'invention concerne une construction polycristalline super-dure comprenant un corps de matériau super-dur ayant une première fraction de grains super-durs dans une matrice d'une seconde fraction de grains super-durs. La taille moyenne des grains de la première fraction est comprise entre environ 1,5 et environ 10 fois la taille moyenne des grains de la seconde fraction, et la première fraction constitue d'environ 5 % en volume à environ 30 % en volume des grains de matériau super-dur dans le corps.
