Electron Microscope with Analytical Facility

The Naval Materials Research Laboratory (NMRL), Ambernath, has acquired an Electron Microscope with Analytical Facility for performing effectively the task of characterisation of metallic materials for microstructure, identification of submicron to nano-meter size second phase precipitates; and quantitative microanalysis of these phases for materials development. The facility consists of LEO-1455 digital scanning electron microscope with Robinson BSD detector and is fully integrated with EDX/WDX/EBSD analytical facilities, which can give a maximum magnification of 3,00,000 X.

The equipment consists of SEM having a LaB6 gun, which can give higher resolution (up to 2.5 nano-meter) than conventional W filament. It has a RBSD detector, which can generate very sharp images based on the atomic number difference of the elements present in the various phases. The equipment has an energy dispersive spectrometer (EDS) with a SATW window for analysis of even lighter elements up to Boron. It has a wavelength dispersive spectrometer (WDS) for micro level analysis of elements in various phases at very low concentration levels. The analytical SEM with such a facility is very useful for high-resolution structural- microanalysis of various materials.
