ILT-U-301
Micro specimen for ferrite count determination
V1: Low carbon steel sample
DETERMINATION | METHOD |
| Preparation and analysis of micro specimen for ferrite count | ASTM E3 and ASTM E407 |
| Correct preparation of the specimen (defined in the first part) Measure the percentage of ferrite.
Quantitative result It will be compared with the result of the reference laboratory (percentage difference). | ASTM E3 and ASTM E407 |
V2: Duplex steel sample
DETERMINATION | METHOD |
| Describe how the sample was prepared and define the metallographic microstructure you see on the micrographs.
The technical expert decide if the metallographic microstructure coincide with the results of the reference laboratory.
Qualitative result It will be compared with the result of the reference laboratory. | ASTM E3 |
| Measure the percentage of ferritic phase.
Qualitative result and Quantitative result It will be compared with the result of the reference laboratory (percentage difference). | ASTM E1245 |
V3: Nickel sample
| DETERMINATION | METHOD |
| Preparation and analysis of micro specimen for ferrite count | ASTM E3 and ASTM E407 |
| Correct preparation of the specimen (defined in the first part) Measure the percentage of ferrite.
Quantitative result It will be compared with the result of the reference laboratory (percentage difference). | ASTM E3 and ASTM E407 |
