The translation of multi-component terms represents one of the most challenging tasks for translators, especially in such fields as metallurgy and steelmaking. In this article, the authors explore various approaches to translating complex terms, which often pose difficulties for translators. Methods such as using equivalent terms and context-based translation are considered. One of the key approaches described in the article is the application of translation transformations and techniques, such as modulation, specification, comprehensive substitution, calquing, and explication, which help improve understanding of complex terms and reduce the number of errors in translation.
