The objective of the work was to develop a standard procedure for the analysis and quantification of the detailed segregation patterns revealed by etch prints using a computer-based image analysis (IA) system. Overall aims of the project were: (i) to develop a technique for quantifying segregation using the image analyser; (ii) to use the technique to identify relationships between segregation in slab and plate, and plate mechanical properties; (iii) to assess the potential of the techniques developed for use as quality control procedures for specific applications. The problems identified in preparing etch prints for image analysis led to the use of etched samples for analysis and quantification. The report details the techniques developed during the project and the results obtained.
