摘要：
The delta ferrite content of certain cast austenitic materials is closely related to their properties. Various etching reagents, especially those based on disulfite, are described which have proved useful in stereometric microstructural analyses. The suitability of the reagents described was confirmed by the relationship between the austenite grain size and the 0. 2 yield stress.
