When the temperature reaches 390ºC, it can be seem from Fig.2 that the diffusion precipitation inside the grains begins to substitute the intermittent precipitation along the boundary of the grains, the tensile strength of the materials become greater, being about 390MPa; when the temperature increases further and reaches 420ºC, the grains after dynamic recrystallization begin to grow, the distribution of the second phase becomes uneven, the tensile strength of the material becomes less than that when the temperature is 390 ºC, the plasticity of the material decreases continuously.

The porosity of powder material can be dictated by the particle packing within the compact before tabletting [2].The properties of tablets are influenced by the porosity of granules.
SEM methods are also applied to investigate the relationship between materials and surface roughness of tablets and contact layers of multilayer tablets.
