My goal is to determine the volume fraction of M23C6 carbide and/or MX carbonitride in the ferritic/martensitic steels. Could I use Raman spectroscopy for this goal? If yes, are there the positive examples of such application of Raman spectroscopy?
Alexandra Fedoseeva, Yes, Raman spectroscopy can be a powerful tool for detecting and quantifying carbide/carbonitride phases like M23C6 and MX in ferritic/martensitic steels.
Proper surface preparation is important for producing acceptable Raman spectra, particularly when investigating carbides/carbonitrides contained in the steel matrix.
