Перспективным способом повышения механических свойств металла шва является реализация механизма дисперсного упрочнения. Реакционное механическое легирование является эффективной технологией получения нанокристалических модифицирующих лигатур и модификаторов. Использование электродов с экспериментальным покрытием, содержащим механически сплавленную, композиционную лигатуру, приводит к устранению транскристаллического типа структуры металла шва и уменьшению размеров зерен в 2,5–3,0 раза (с No 8–9 до No 11–12), что обеспечивает снижение на 20–30% порога хладноломкости и увеличение на 15–25% механических свойств металла шва. Actual problem of modern welding production is the creation of electrodes for maximum performance and efficiency of the process whithin the required reliability and durability of the structure. A promising way to improve mechanical properties of the weld metal is the implementation of the mechanism of dispersion hardening. Reactionary mechanical alloying is an effective technology of obtaining nanocrystalline modifying ligatures and modifiers. The use of electrodes with an experimental coating containing a mechanically alloyed, composite ligature to resolve transcrystalline type of structure of the weld metal and reduce the grain size by 2.5–3.0 times (from # 8–9 to #11–12) reduces by 20–30% the threshold of cold brittleness and increase by 15– 25% of the mechanical properties of the weld metal.","PeriodicalId":30904,"journal":{"name":"Lit''e i Metallurgia","volume":"1 1","pages":"102-108"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68013480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
