Surfacing of Cr–Ni–Ti–Fe powder compositions is carried out using an ELV‑6 industrial electron accelerator providing the possibility of emitting electrons into an air atmosphere. This work sets out to develop high-quality surface layers with the properties corresponding to those of chromium-nickel austenitic steels. To that end, the phase composition and elemental distribution of alloying components in coatings are evaluated; structural features are analyzed; mechanical and adhesion characteristics of the deposited materials are determined. Coatings with a thickness of 1800–2700 µm are shown to be formed on the surface of steel. The coatings are characterized by a dendritic structure. According to X‑ray diffraction analysis, the dendrite grains are a γ-solid solution based on Ni and Fe. The maximum strength of ~900 MPa is observed in one-layer coatings. An increase in the concentration of alloying elements during the formation of two-layer coatings leads to a decrease in strength to 580 MPa. At the same time, the relative elongation is 28%. The adhesion strength of the coating with the base material reaches 560 MPa. In addition, alloying the surface of 12KhN3A steel with chromium and nickel makes it possible to increase its corrosion resistance in concentrated nitric acid.</p></div>","PeriodicalId":702,"journal":{"name":"Metallurgist","volume":"68 11","pages":"1702 - 1711"},"PeriodicalIF":0.8,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145165001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The metallurgical industry, which consumes significant energy and material resources while generating large volumes of challenging-to-recycle waste, also requires the gradual integration of innovative solutions to reduce production costs for metal products. A promising approach to address some of the existing challenges in the iron and steel industry is the aluminothermic process, based on redox reactions in thermite mixtures at temperatures exceeding those used in conventional electrometallurgical melting. This method significantly reduces energy consumption in metal production. In addition, it facilitates the incorporation of metallurgical and mechanical engineering waste into thermite compositions, thereby reducing reliance on expensive and scarce charge materials. The properties of the resulting alloys can be regulated through the parameters of the aluminothermic process, which primarily depend on the characteristics of the raw materials used to form the thermite mixtures. One approach to tailoring the properties of the final materials involves varying the fractional compositions of the reducing agent (RA) and mill scale (MS), which affects the combustion temperature, reaction rate, structure, elemental composition, and crystallization and cooling conditions of the billets. The findings demonstrate the feasibility of effectively managing the properties of alloys produced by aluminothermy. The results, presented as graphical dependencies, photomaterials, and conclusions, hold significant scientific and practical value for enterprises in various processing industries.</p></div>","PeriodicalId":702,"journal":{"name":"Metallurgist","volume":"68 11","pages":"1743 - 1755"},"PeriodicalIF":0.8,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145165009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that the main conditions for increasing the heat resistance and operational properties of surface layers in laser irradiated materials are related to features of their structural state. These features include a fragmented texture of basic phases and an increased density of defects in the crystal structure of solid solutions. The impact of laser hardening on the heat resistance of steels is characterized by a reduction in the rate of decomposition of martensite. The main reason for this is the formation of segregations (clusters, atmospheres) of carbon atoms and alloying elements on dislocations in the α‑solid solution lattice. Additionally, these segregations exhibit stable existence at higher heating temperatures in comparison to structures obtained by bulk hardening. It is shown that after laser treatment, additional possibilities for improving the set of properties of the irradiated metal are provided by multiple formation of nano-sized carbide precipitates on dislocations during thermal action, i.e. nanoprecipitation. Laser irradiation also reduces the tendency of carbide phase precipitates to coagulate and slows down the rate of hardness decrease with the increase of heating (tempering) temperature. The texture effects observed in austenite and martensite in laser hardened steels persist when heated to high tempering temperatures. These effects lead to anisotropy of properties, particularly a significant reduction in the coefficient of friction in tribocouplings. Pulsed laser treatment of steels allows the hardness of irradiated areas to increase to 8–11.5 GPa and heat resistance to improve by 50–120 °C. This contributes to the enhanced performance of irradiated products.</p></div>","PeriodicalId":702,"journal":{"name":"Metallurgist","volume":"68 12","pages":"1906 - 1913"},"PeriodicalIF":0.8,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
