Structure, Mechanical Properties, Elemental Composition of Phases and Micromechanism of Crack Growth in Alloy AK9Ch Subjected to Homogenizing Treatment and Modifying

The structure and mechanical characteristics of alloy AK9ch are studied after different treatments involving homogenization and modification of the melt. The micromechanism of crack growth in alloy AK9ch after the treatments is investigated. The composition of the phases is studied quantitatively with plotting maps of the distribution of elements in them. The changes in the morphology of the individual phase components due to the modifying and due to joint homogenizing and modifying are determined.
