title: Optical microscopy of isothermally decomposed beta copper based SM alloys.
abstract: The usefulness of two etching procedures for revealing the microstructural features in thermal treated beta copper-based SM alloys is shown. Colour etching is used to improve the detection of the phases and achieve a higher accuracy in their identification.
