TLDR
In this article, the performance of the premixed (elemental) 6061 Al powder with and without sintering aids was investigated and it was found that additions of ∼0.12% Pb was the most effective and enhanced the response by obtaining almost a full sintered density (∼2.7"g/cm 3 ) with a corresponding increase in the hardness and tensile strength values as compared to the base 6061Al alloy powder mixture without Pb addition.About:

Structure and strength of aluminum with sub-micrometer/micrometer grain size prepared by spark plasma sintering
TL;DR: In this paper, a spark plasma sintering (SPS) technique has been applied to prepare fully dense Al samples from Al powder, and the results showed that SPS is an excellent technique for the production of very fine grained Al materials with high strength, by combining both grain boundary and oxide dispersion strengthening.

The effect of solubility and particle size on liquid phase sintering
Roger N. Lumley,G. B. Schaffer +1 more
TL;DR: The use of fine additive powders in systems having a substantial transient aspect results in a greatly reduced quantity of liquid phase formed during sintering, whereas the use of coarse powders increases the amount of liquid phases that forms and prolongs its existence during sinthing as discussed by the authors.
