Mean Atomic Number Quantitative Assessment in Backscattered Electron Imaging
(Cambridge University Press, 2012-12)
A method for obtaining quantitative mean atomic number images in a scanning electron microscope for different kinds of samples has been developed. The backscattered electron signal is monotonically increasing with the mean ...
Correlative light-electron fractography for fatigue striations characterization in metallic alloys
(2013-09-01)
The correlative light-electron fractography technique combines correlative microscopy concepts to the extended depth-from-focus reconstruction method, associating the reliable topographic information of 3-D maps from light ...
