Specific features of the behavior of elements during precipitation, which are necessary to know when preparing selective REM and manganese concentrates, have been revealed. At pH 5.25, 85% ΣTR2O3 pass to a deposit (in the oxide formula, ΣTR is the commonly accepted international designation of REMs), and the REM content is 60.5%. At pH 5.25–7.4, 92% manganese are extracted to a manganese concentrate, and the MnO content in the concentrate reaches 70.7%. The complicated chemical composition of the solution requires three-stage fractional precipitation for preparing qualitative selective concentrates: iron and thorium should be precipitated as a cake at the first stage, and REMs and manganese should be precipitated at the second and third stages, respectively. This makes it possible to form deactivated concentrates in the form of carbonates suitable for the further extraction of REMs and manganese by the well-known methods.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142412664","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}

Cu–Co and WC–Cu–Co alloys are fabricated by reactive infiltration of liquid copper into uncompacted WC and Co powders under LFV of their compositions (80 Hz for 10 min at 1300–1350°C). Their phase and chemical compositions, structure, and hardness have been studied. We are the first to experimentally show that metastable formations (frozen immiscibility regions of two liquids) are the precursors of (Co) dendrites and have the same composition with them. The cobalt distribution over the height of Cu–Co alloy ingots and over phase components is shown to depend on the cobalt content, the effect of vibration, the geometric arrangement of initial component layers, and the temperature. The optimum conditions for achieving a uniform cobalt distribution over the melt have been determined. Cobalt is shown to ensure precipitation hardening of the Cu–Co metal binder due to the formation of (Cu) solid solutions already at the stage of synthesis of Cu–Co and WC–Cu–Co alloys. Moreover, the potential for additional hardening by subsequent heat treatment or by changing cooling conditions is still incompletely fulfilled.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142412628","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}

When the reduction increases, the fraction of the γ phase decreases from 82% in the initial hot-rolled state to 74% at a 10% reduction and to 60% when the reduction increases to 70%. The type of austenite texture is characterized by the components typical of the rolling texture of fcc metals, namely, the “brass” texture ({110}〈112〉). It does not change at a 10% reduction, then increases significantly at a 20% reduction, and remains the same up to a 70% reduction. The texture of the α phase is characterized by three components, namely, {110}〈110〉, {211}〈110〉, and {001}〈110〉. The first two components are the transformation textures, which dominate in the initial state; after a reduction of 30%, the third component, which corresponds to the rolling texture of the bcc α phase, increases. The estimation of residual stresses shows that compressive stresses of 600–1100 MPa form in the γ phase and tensile stresses of 1200–1600 MPa form in the α phase.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142412629","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}
