Application of Quantitative Metallographic Analysis Technique in Metallographic Examination of Nodular Cast Iron

As a new metallographic analysis technique based on computer science and pattern recognition technology,quantitative metallographic analysis technique was introduced in the metallographic examination of nodular cast iron. Comparing with traditional analytic procedure which assesses metallographs by standard images antitheses according to GB/T 9441-1988,quantitative metallographic analysis technique is featured with quantitative calculation,easier handle,more accuracy and less artificial error.
