Green compact density
WebPowder Sintering . Powder sintering involves raising the temperature of the green compact, (pressed powder part), to a certain level and keeping it at that temperature for a certain amount of time. The sintering temperature … WebMost of powder compaction techniques lead to green compacts require sintering in order to gain high density and strength of the product. By using dynamic compaction systems, it is possible to attain a density very close to the theoretical density of the material without needs to sintering process [1–4 ].

WebThe green density of the compacts was calculated from the volume and mass of the pressed compacts. The pressed samples were weighed with a precision mass balance. The volume of the compacted samples was calculated from the diameter and height measured with a vernier calliper. WebGreen compacts are heated in a controlled atmosphere furnace to temperature below the melting point, but sufficiently high to allow bonding of the individual parts.
WebGreen density is measured by the Archimedes principle. Green parts are oil impregnated before the density is measured.

Webdensity distribution isnonuniform but completely known. Then, for prescribed geometries of the compact, powder properties, and coefficients of friction between the powder and both the outside die wall and the inside core rod, the solution described here predicts the axial and radial variations of the density throughout the green compact. WebTable 2 shows the green density obtained for NM9620 compacted powder is higher for compaction temperature at 150 o C, which is 2.51 g/cm 3 , compared to the 2.37 g/cm 3 green density obtained for ...
WebTo produce a homogeneous green compact microstructure and avoid microscopic density gradients, granules should be strong enough to allow significant rearrangement prior to deformation/fracture (i.e., to pack more efficiently), but weak enough to completely break down, deform, and knit together to produce a uniform microstructure during ...
