What is special about the dark-field electron microscope micrograph? Correct Answer Precipitates can be imaged bright and matrix dark

The so-called dark-field electron microscope micrograph in which the precipitates are imaged bright and the matrix dark. The precipitates lie in rows along dislocations. And this can be used in case of niobium carbonitride precipitates on dislocations in a ferritic iron matrix
