Abstract
(EN)
Provided is a powder material that is for producing a molded article that has low porosity but has uniformly distributed micropores by means of a powder laminate molding method. A powder material that is to be used for powder laminate molding, the powder material including ceramic and metal, and the tapped fill rate of the powder material, defined as (tapped density/theoretical density)×100%, being at least 30% but less than 40%.
(FR)
L'invention concerne un matériau en poudre qui est destiné à la production d’un article moulé présentant une faible porosité, mais comportant des micropores uniformément répartis au moyen d'un procédé de moulage de stratifié à partir de poudres. L’invention concerne donc un matériau en poudre destiné à être utilisé dans le moulage de stratifié à partir de poudres, le matériau en poudre comprenant de la céramique et du métal, et le taux de remplissage tassé du matériau en poudre, défini par (densité tassée/densité théorique)×100 %, étant d'au moins 30 % mais inférieur à 40 %.
(JA)
