By analyzing the wavelet phase-frequency and phase-time characteristics of the group of hydrometric characteristics of the world water balance, heliocosmic and climatic variables in the phase-frequency and phase-time domains, the dependences of changes in the hydrometric characteristics of the world water balance by changes in heliocosmic and climatic variables in the phase-frequency and phase- temporary areas. These dependencies are presented in two figures with many graphs and two correlation matrices. They characterize the variability of the components of the world water balance by changes in heliocosmic and climatic variables in two areas in the observed time interval and are reflections of changes in the self-organizing climate system. In changes in the phase-time characteristics of groups of factors, lattice structures of differently and unidirectional changes in variables are observed, which characterize the cyclical nature of climate changes on Earth.","PeriodicalId":375097,"journal":{"name":"Yugra State University Bulletin","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133817428","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 hardness of the samples was determined on a hardness tester ZIP TK=2M using the Brinell method according to GOST 9012-59.

The weldability of the composite was rated as satisfactory. Highly dispersed particles of the reinforcing phase do not dislocate from the area of ​​the base metal to the area of ​​the weld. The hardness of the composite material after argon-arc welding does not fall, but remains at the same level. The porosity in the weld zone of the composite is less than in the weld zone of the matrix alloy.","PeriodicalId":375097,"journal":{"name":"Yugra State University Bulletin","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127840135","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}
