Research of the Microstructure of Fe30Cu70 Alloy Obtained by Different Technologies

Steel in Translation Aims and scope

Abstract

The influence of manufacturing material methods based on Fe30Cu70 on their microstructure and inclusion size, which is determined by the cooling rate of the melt during crystallization, is investigated. The line structure of the solid phase microstructure enriched in iron in the early stages of cooling can be traced with all the technologies for producing the Fe30Cu70 alloy. It was found that the higher the cooling rate, the less manifested was the network nature of the structure. An elemental analysis of the structure showed that the content of iron and copper in all structural components is greater than the maximum possible mutual solubility of the elements.
