However, the currently known and used plastic flow regularities and RS experimental determination methods in most cases have a significant disadvantages: labor intensity, low accuracy, sample preparation necessity and difficult to apply on real parts. This work purpose is to develop special equipment and methods for researches by the digital image correlation method for conducting experimental metal plastic flow and RS researches during free orthogonal cutting and surface plastic deformation (SPD) under the technological treatment factors variation. The paper substantiates orthogonal loading schemes in the metal plastic flow research in the cutting and SPD processes, research accessories and equipment is developed. The machine movement errors were determined, the sample sizes and loading routines were determined and justified. Using the digital image correlation method, the metal plastic flow experimental researches in the deformation zone during free orthogonal cutting and surface plastic deformation processes were performed. For experimental samples RS determinination after free orthogonal cutting and surface plastic deformation, the digital image correlation and probing hole drilling methods combination was used for the first time, which idea is to determine the material particles movements on the sample top from two images: the sample surface having residual stresses and the same surface after high-speed probing hole.","PeriodicalId":178558,"journal":{"name":"Strengthening Technologies and Coatings","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136003047","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 deposited layer was obtained using submerged arc surfacing by the ASAW-1250 welding tractor using a fabricated flux-cored wire made from slag produced by silicomanganese with a chemical composition, mass. %: 0.50 FeO; 15.16 MnO; 29.13 CaO; 42.40 SiO2; 6.80 Al2O3;1.39 MgO; 0.18 Na2O; 0.59 K2O; 0.28 S; 0.022 P; 0.004 ZnO; 0.024 C; 0.32 F; 0.17 TiO2; 0.033 Cr2O3. The studies carried out made it possible to establish the relationship between the chemical composition of the deposited flux-cored wire and the structure and properties of the deposited metal. It has been established that the introduction of titanium increases the values of hardness and microhardness. The use of a carbon-fluorine-containing additive leads to microstructural changes expressed in obtaining the structure — ferrite, perlite and bainite, in contras t to the structure — martensite, δ-ferrite and residual austenite, as well as to an increase in the size of martensite needles in the structure of the deposited layer. Microstructural changes are due to the introduction of a carbon fluorine-containing additive into the composition of flux-cored wire and are accompanied by a change in microhardness and hardness. With an increase in the content of the carbon-fluorine-containing additive in the composition of flux-cored wire, an increase in the microhardness and hardness of the deposited metal is observed.","PeriodicalId":178558,"journal":{"name":"Strengthening Technologies and Coatings","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135956507","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}

There are also copper oxide particles in the coating. A transition area with a thickness of 100...150 nm, which has a complex structure, is formed on the boundary between the coating and the substrate. The silver grains in the coating have a platelet structure, and the copper substrate has a subgrain structure. The hardness and Young's modulus of the \"coating (Ag-C)/(copper) substrate\" system increase with the distance from the surface to the boundary between the coating and the substrate.
