From Nanostructured Powders to Dense Nanostructured Materials : Mechanically Activated Powder Metallurgy

摘要

The mechanical activation of powder metallurgy processing has been found to lead to the synthesis of nanostructured micrometer powders (ERAM / M2AP process). Homogeneous but porous nanomaterials can be obtained by the MASHS process. Recently, such an activation step to self heat sustaining reaction has been found to lead to the synthesis of fully dense bulk nanostructured materials (so called MAFAPAS, patented process).
