Conclusions
Samples 8-1, 8-4, 8-6, 8-8, 8-10 had comparable properties to EBS.
8-1 and 8-4 were unacceptable for sintering because of Low TRS
strength.
8-6, 8-8, 8-10 showed similar hardness and density, but had higher
sintered Dimensional Change, Lower TRS, and some evidence of
residue on the surface. Based on the similarity of results between
these three samples, they appear to be similar in composition.
I think we should focus on these three samples, and try to figure out
where the delubing issue is coming from. We may solve the other
problems once we determine why we are having residue.
