A simple adaptation of the carbon replica technique for the examination of selected areas in the electron microscope

The value of electron microscope replica techniques, particularly in metallurgical applications is greatly enhanced if it is possible to examine areas or features selected in the optical microscope. Though existing methods can be used to achieve this with the carbon replica, it has been found that they are not entirely suitable. The paper describes a simple and quick method for use with carbon replicas. To illustrate a possible field of application, a selected area of a pearlitic steel specimen is examined at different stages during etching treatment.
