GB/T 9441-2021 Metallographic test method for spheroidal graphite cast iron
Abstract
This document specifies the calculation of the spheroidization rate of nodular cast iron, the preparation of metallographic samples, the inspection rules, the inspection items and rating charts, the presentation of results, and the inspection report.
This document specifies the methods of evaluating the microstructure of nodular cast iron by visual inspection and evaluating the spheroidization rate of nodular cast iron by computer image analysis software.
This document is applicable to the evaluation of the metallographic structure of as-cast, normalized, and annealed nodular cast iron.
