Far-reaching examinations
to various topics

English
Under the following references some examinations are listed. These examinations
are to extensive for the presentation in the material card index. On the other hand,
it is usually fundamental occurences and forms of microstructure these happen at a
variety of materials.
At the enlarged views a measuring function is available.
The measuring spots 1 and 2 get specified with the left mouse button and the distance
between them gets computed on base of the magnification scale. An optical measuring
point marking takes place on the screen by means of little measuring crosses. For the
use of the measuring function you must activate Javascript in your Browser.
Measuring accuracy of the different magnifications:
12,5 : 1 ca. 9 µm
50 : 1 ca. 2 µm
100 : 1 ca. 1 µm
200 : 1 ca. 0,5 µm
500 : 1 ca. 0,2 µm
1000 : 1 ca. 0,1 µm
For the determination of the through-hardenability at steels the end quench sample, also Jominy sample named, is used.
Microstructure examinations at Jominy or end quench test sample
In the steel can be found different strong concentration
differences of the alloying elements. In the following are some examples about segregation
distribution to see.
