A method of hot rolling of reinforcement with a double‑sided crescent (2f) profile is proposed; technological factors influencing the strength, plastic and operational properties of reinforcing bars through the formation of its effective microstructure are considered. The chemical composition of steel was proposed and modes of thermomechanical hardening of reinforcement with rolling heating were developed, providing high consumer properties. The results of mechanical tests of rolled reinforcing bars in coils and comparative data on the mechanical properties and geometric parameters of the reinforcement are also presented.","PeriodicalId":506783,"journal":{"name":"Litiyo i Metallurgiya (FOUNDRY PRODUCTION AND METALLURGY)","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140716828","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}

The dependences for technical characteristics and physical properties of the cores on the mass fractions of ultra‑fine powders based on aluminum, steel, and bronze are established. The significant reserves for improving a knocking‑out ability of the cores based on promising compositions for cast iron by adding ultra‑fine powders of aluminum or bronze into core mixtures are revealed. It is established that the best knockingout ability of the cores in combination with a low outgassing rate and a high gas permeability can be achieved by combining 15.0 wt. % crushed seashell and 0.5–1.0 wt. % aluminum powder. The boundaries for reasonable use of a recycled mixture in preparation of a core mixture are determined.","PeriodicalId":506783,"journal":{"name":"Litiyo i Metallurgiya (FOUNDRY PRODUCTION AND METALLURGY)","volume":"163 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140719776","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}

Из них образуются фотонные электроны и позитроны, из которых формируются фотонные протоны и нейтроны. Последние образуют фотонные ядра. Они захватывают фотонные электроны и формируют атомы фотонной материи, из которых образуется вещественная материя, изучаемая и используемая людьми. Из фотонной материи состоит тело человека и весь вещественный мир. Элементарными строительными частицами нейтринной материи являются отрицательный, положительный и нейтральный нейтрино. Образуемые из них нейтринные электроны и позитроны формируют нейтринные протоны и нейтроны – основу нейтринного ядра. Они захватывают нейтринные электроны и формируют атомы нейтринной материи, из которых образуется духовная материя, не изучаемая людьми. Из нейтринной материи состоит душа человека и весь духовный мир. Показано, что душа человека в 10000 раз легче его тела.
