Microstructure of cast irons - Part 3: Matrix structure (ISO/TR 945-3, IDT)
This Technical Report gives the designations, descriptions and reference micrographs of the matrix structures of cast irons.
It applies to the following types of cast irons:
— grey cast irons (Table 4.1);
— spheroidal graphite cast irons (Table 4.2);
— austenitic cast irons (Table 4.3);
— malleable cast irons (Table 4.4);
— compacted (vermicular) graphite cast irons (Table 4.5);
— ausferritic spheroidal graphite cast irons (Table 4.6);
— abrasion-resistant cast irons (Table 4.7).
Each matrix structure is defined with explanations and micrographs.
Unless otherwise stated in Clause 4, the micrographs shown correspond to samples etched with a solution of 2 % nitric acid in ethanol (Nital).
