Abstract

L'invention concerne un matériau métal nanocristallin en vrac comprenant un agrégat de grains nanocristallins métalliques ainsi qu'un oxyde, nitrure, carbure, borure ou équivalent d'un métal ou métalloïde entre les grains nanocristallins susmentionnés et/ou dans ces grains comme substance inhibant la croissance du grain cristallin. L'invention concerne également un procédé de production de ce matériau métal nanocristallin en vrac qui consiste à soumettre les poudres fines respectives des composants du matériau métal nanocristallin en vrac à un alliage mécanique (MA) à l'aide d'un broyeur à billes ou équivalent pour préparer des poudres de nanométal et puis à soumettre les poudres à un traitement de malaxage et de façonnage tel qu'un malaxage et un façonnage à chaud, par exemple, un frittage au plasma par étincelle, l'extrusion ou laminage, ou formage par explosion. Le matériau métal nanocristallin en vrac a une grande dureté élevée, résistance et ténacité.
