{"title":"Basics of Additive Manufacturing Processes for High-Entropy Alloys","authors":"","doi":"10.15407/ufm.24.03.561","DOIUrl":"https://doi.org/10.15407/ufm.24.03.561","url":null,"abstract":"). Thus, ∆ S conf for equimolar alloys with 3, 5, 6, 9, and 13 elements equal to 1.10 R , 1.61 R , 1.79 R , 2.20 R , and 2.57 R , respectively. In addition, if the formation enthalpies of two strong intermetallic compounds ( e.g. , NiAl and TiAl) are divided by their respective melting points, the resulting ∆ S conf , 1.38 R and 2.06 R , belong to the same range as the entropy changes of mixing in a system with more than five elements [1]. This evidences that the tendency to ters such as laser power, scanning speed, and powder­feed rate are analysed for their influences on the microstructure and mechanical properties of the final pro­ duct. The post­processing techniques for additive­manufactured HEAs are conside­ red. The importance of steps such as heat treatment, surface finishing, and machin­ ing in achieving the desired material properties and dimensional accuracy in AM­ produced HEA components is underlined. Overviewing the HEAs, their application in AM processes, the influence of process parameters, and post­processing consi­ derations, this work can act as a useful source of information for researchers on the way to amendment of the understanding and implementation of AM in the HEAs.","PeriodicalId":41786,"journal":{"name":"Uspekhi Fiziki Metallov-Progress in Physics of Metals","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135348120","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}

Influence of Modification on the Characteristics of Reinforcing Steels Intended for Reinforced Concrete Structures 改性对钢筋混凝土结构用钢筋性能的影响

{"title":"Influence of Modification on the Characteristics of Reinforcing Steels Intended for Reinforced Concrete Structures","authors":"","doi":"10.15407/ufm.24.03.470","DOIUrl":"https://doi.org/10.15407/ufm.24.03.470","url":null,"abstract":"We review and analyse the reasons of destabilizing the chemical composition and me­ chanical characteristics reinforcing low­carbon steels and present ways to solve these problems. As determined, both the instability of the chemical composition and the non­metallic inclusions of an elongated and acute­angled shape, containing an exces­ sive amount of gas and other impurities, reduce the service life of the finished me­ tallurgical product and lead to a deterioration in the quality of the finished product. As established and proven, one of the ways to maximize the chemical­composition stabilization and to improve mechanical characteristics, as well as the quality of the reinforcement, is the steel­melts’ processing with multifunctional­action modifiers. As determined, the St1kp steel, like other low­alloy steels, is a multicomponent system consisting of 17 or more components. Each of the impurities, as well as deo­ xidizing modifier elements (Al, Ti, Mg), can change significantly the composition of non­metallic inclusions, the main matrix, cementite, grain size, mechanical charac­ teristics, and their stability. As established, after modification, the St1kp­steel grain structure is almost 2 times finer, after which it can be asserted safely that such a material can last longer. As revealed, all mechanical­characteristics’ parame­ ters of the modified metal met the requirements of the State Standards (DSTU) 2770­94 and exceed the serial ones. This is especially important for reinforced con­ crete structures, since the insufficient level of mechanical characteristics and their instability cannot guarantee the reliability and durability of their operation. As noted, during the solidification of the modified ingot, mainly volumetric crystalli­ zation takes place,","PeriodicalId":41786,"journal":{"name":"Uspekhi Fiziki Metallov-Progress in Physics of Metals","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135348113","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}
