The analysis is carried out using the transmission electron microscopy. The type St3 steel is used for the welding material. The effect of plastic deformation is determined for the material morphology, phase composition, defect structure, and its parameters. Investigations are conducted at 1 mm distance between weld and base metals at the deformation degree ranging between 0-5%. Plastic deformation does not lead to a structural quality modification (hypopearlitic steel structure is present as before), while the qualitative parameters are changed such that a portion of the perlite component becomes more defective and first transforms to fractured perlite and then ferrite, and the perlite volume fraction then decreases. Polarization of the dislocation structure is observed, however, does not induce internal stresses capable to disintegrate the specimen.","PeriodicalId":423038,"journal":{"name":"2015 International Conference on Mechanical Engineering, Automation and Control Systems (MEACS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131415424","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 data obtained on stressed-deformed body underframe in the result of shocks are of local character for the body structure. Normal stress values in underframe beam cross-sections depend on the cargo block falling place: the maximum stress - if there is impact on longitudinal support beams and the minimum - if the is falling on the joint of intermediate and longitudinal beams. Steel dynamic yield stress is assumed as allowed stress values.","PeriodicalId":423038,"journal":{"name":"2015 International Conference on Mechanical Engineering, Automation and Control Systems (MEACS)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121935206","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}
