Hi,
have a few questions on Konstantina's and your report.

1.  If you place steel bars or steel nets in the concrete, the strength will 
increase significantly, but the IMC plates and needles in the sollder joint 
do the opposite. How com?

2. Why are so many geometries created? Large plates, small plates, needles, 
bars, all in a chaotic oder.

3.  What causes the predominant brittleness, size of IMCs or geometric form 
or  anything else?

4. What is the major driving force to build up the IMC structure, 
percentage of xx in the solder, or solidification speed or what?

Inge
