Abstract:
(EN) The present invention provides a metal laminated shaped article that includes aluminum and that is sound and free of defects. The metal lamination shaping powder according to the present invention for shaping this metal laminated shaped article is an aluminum-based powder having a 50% particle size of 10 µm to less than 100 µm on a volume basis when the particle size distribution is measured by a laser diffraction/scattering method, a specific surface area of 0.5 m2/g or less, and an oxygen amount per unit surface area of 30 mg/m2 to 100 mg/m2, the relationship between the hydrogen amount (X mL: standard state) per 100 g of the aluminum-based powder and the specific surface area (Y m2/g), and the relationship between the hydrogen amount (X mL: standard state) and the oxygen amount (Z weight%) being represented by X/Y < 151 and Z/X > 0.0022. A metal laminated shaped article shaped through use of a three-dimensional lamination shaping device using this metal lamination shaping powder by a powder-floor melt-bonding system has a hydrogen content of 3 mL or less per 100 g (standard state) and a relative density of 99% or greater.
(FR) La présente invention concerne un article façonné stratifié métallique qui comprend de l'aluminium et qui est sain et exempt de défauts. La poudre de façonnage par stratification métallique selon la présente invention pour le façonnage dudit article façonné stratifié métallique est une poudre à base d'aluminium possédant une taille de particule à 50 % de 10 µm à moins de 100 µm sur une base volumique lorsque la distribution de taille de particule est mesurée par une méthode de diffraction/diffusion laser, une surface spécifique inférieure ou égale à 0,5 m2/g, et une quantité d'oxygène par surface unitaire de 30 mg/m2 à 100 mg/m2, la relation entre la quantité d'hydrogène (X ml : état standard) pour 100 g de la poudre à base d'aluminium et la surface spécifique (Y m2/g), et la relation entre la quantité d'hydrogène (X ml : état standard) et la quantité d'oxygène (Z % en poids) étant représentées par X/Y < 151 et Z/X > 0,0022. Un article façonné stratifié métallique façonné par le biais d'un dispositif de façonnage par stratification en trois dimensions au moyen de ladite poudre de façonnage par stratification métallique par un système de liaison par fusion du fond de poudre possède une teneur en hydrogène inférieure ou égale à 3 ml pour 100 g (état standard) et une densité relative supérieure ou égale à 99 %.
(JA) 本発明は、アルミニウムを含む欠陥の無い健全な金属積層造形物を提供する。本金属積層造形物を造形する金属積層造形用粉末は、レーザー回折・散乱法で粒子径分布測定した場合の体積基準の50%粒子径が10μm以上100μm未満、比表面積が0.5m2/g以下で、かつ、単位表面積当りの酸素量が30mg/m2以上100mg/m2以下のアルミニウム系粉末であって、アルミニウム系粉末100g当りの水素量(Xml:標準状態)と比表面積(Ym2/g)との関係、および、水素量(Xml:標準状態)と酸素量(Z重量%)との関係が、X/Y < 151、Z/X > 0.0022、で示される。そして、この金属積層造形用粉末を用いて、粉末床溶融結合方式による3次元積層造形装置により造形した金属積層造形物は、水素含有量が100g当り3ml以下(標準状態)、かつ、相対密度が99%以上である。
