Hey Christian, Hey Larry

thanks for your quick respons.

We are having an alloy which is pressed out of grains. And depending the parameters there are sometimes more and bigger pores and sometimes not. So  I want to determine the  porosity depending the used parameters.
Furthermore I am interested in the percentage area of the particles  to sort them better out.

Christian I think u mean something like this here: (I shortend it and just listets area and %area) right?

   Area       %area
1    12        100
2    12        100
3    12        100
4    446       100
5    12        100


And here I was wondering why it always says 100% in %area, no matter what size the particle has.
So do I have this right, in your opinion I should just take the values which are presented in the gap "area" and calculate the %area on my own?

Thanks in regard.
Kathrin
