accordance to E45method D
Normally the test sample is carbon steel.
1. I polished the test sample's surface to 0.06µm.
2. observed the surface under 100X.
The difficulties or doubts that i'm facing:
1. The sample will rust, some dots on surface, is very hard for me to
determine which 1 is inclusion.
2. How to differentiate silicate and sulfide? (refer to Plate I-r)
3. How to differentiate aluminate and oxide?
4. after i polished, all the black dots or lines on surface are
inclusions?
5. Is there any link or good book for reference.
Thanks in advance. :)
