TWA 37

Quantitative Microstructural Analysis

Cr distribution in a corroded steel sample

The objective of this TWA is to develop harmonised test procedures for quantitative microstructural analysis using microbeam instruments such as a transmission electron microscope, scanning electron microscope and electronprobe microanalyser.

Activities will include interlaboratory comparison studies of measurement methods and pre-normative research required for the development of robust international standards. The main output for the work will be to support the work of ISO TC 202 on Microbeam Analysis.

PROJECT 1 :Determination of reproducibility and repeatability of grain size measurement by Electron Back Scattered Diffraction (EBSD)

PROJECT 2 : Investigation of sharpness of scanning electron microscope (SEM) images

PROJECT 3: Development of guidelines for reproducible TEM specimen preparation by focused ion beam processing

PROJECT 4:Measurement of dislocation density in metallic materials by Transmission Electron Microscope (TEM)

PROJECT 5:Repeatability of high angular resolution electron backscatter diffraction (HR-EBSD) analysis for elastic strain measurements

PROJECT 6:Mesurement of grain size and distribution of nano-scale metal using Transmission Kikuchi Diffraction technique in SEM
