Abstract
This study aims to develop a method for on-site metallography, enabling the characterization of carbide banding in cold-work steels via cellulose acetate film replication. It will be demonstrated that for this purpose, it is sufficient to grind the sample surface using P1500 mesh SiC abrasive paper and etch it with V2A etchant or nitric acid for 7 minutes. By sample preparation and etching, the matrix of the parent material is sufficiently removed for the carbides to leave a "negative"impression on the film. This negative replica can then be studied under reflected light microscope, enabling the characterization of carbide banding. © 2022 Walter de Gruyter GmbH, Berlin/Boston, Germany.
