Why on earth copper-graphite composites expand after conventional sintering process?

Copper was in powder form, graphite was in fiber form (150microns), uniaxial compacted in 12mm mold under 5 tonnes of load. Sintering at 900 deg C under argon atmosphere.

What is the best method to measure lattice constants and crystallite size of graphite fiber?

I need to measure the lattice constants of graphite fiber using xrd. Based on the xrd spectrum, only 002 peak is clearly visible. The 004, 110, 112 & 006 peaks are so weak. Any suggestion to...

Does storage modulus of copper measured from tensile test equivalent to one measured from 3-point bending?

I am trying to measure the storage modulus of copper at elevated temperature using DMA. But my sample is not thin enough so I have to use 3 point bending instead of tensile test. Will I get the...
