Provides the designations, descriptions and reference micrographs of the matrix structures of cast irons.

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).
