Results
obtained with UniQuant 1 on 1989-April-23
A piece of steel with the shape of a cylinder had to be
analysed.
The material was so hard that sample preparation would
hardly be
possible.
The dimensions of the sample: 20 mm length, 8 mm outer
diam.
3 mm inner diam. The sample was analysed at one of its
end surfaces. |
