A plurality of particles (12) include a first material. A coating (14) including a second material is formed on surfaces of the particles, until a selected ratio of the volume of the coating relative to the volume of the particles is achieved. A plurality of particles, including the coated particles (10), are consolidated in a manner such that the particles are caused to be joined to each other, to form an article. The ratio of the volume of the coating relative to the volume of the particles is selected in a manner such that the article is engineered to have a selected volume fraction presenting the volume of the second material in the article relative to the volume of the first material in the article. The first material, the second material, and the volume fraction are selected in a manner such that the article is engineered to exhibit a selected intrinsic property.

Une pluralité de particules (12) comprennent un premier matériau. On applique sur la surface des particules un revêtement (14) comprenant un second matériau, jusqu'à ce qu'on atteigne un rapport déterminé entre le volume du revêtement et le volume des particules. On consolide la pluralité de particules, y compris les particules revêtues (10), de façon que, une fois réunies, elles constituent un article. On détermine le rapport entre le volume du revêtement et le volume des particules afin de modifier l'article de façon qu'il présente une fraction de volume déterminée représentant, dans l'article, le volume du second matériau par rapport au volume du premier matériau. On choisit le premier et le second matériaux, de même que la fraction de volume, de façon à modifier l'article pour qu'il présente une propriété intrinsèque déterminée.
