Examples of Phase Decoration
Depending upon the steel composition, a variety of procedures can be used to decorate the prior-austenite grain boundaries –if the steel can be heat treated. Examples include ferrite or cementite decorating the grain boundaries after slow cooling or after carburizing, or using the oxidation method. If the specimen can not be heat treated, as in failure studies, we can only use etchants to bring out the prior-austenite grain boundaries.
