It is believed that high mechanical properties of HEAs are provided mainly due to the fact that the presence of dissimilar atoms of elements with different electronic structures, size and thermodynamic properties in the crystal lattice of the solid solution of substitution leads to its significant distortion and slow diffusion of atoms in a multicomponent elemental matrix. This contributes to significant solid solution hardening and thermodynamic stability of properties, provides increased thermal stability of the phase composition and structural state, and, consequently, high alloy properties hardness, strength, wear resistance, oxidation resistance, etc. The high entropy of mixing elements in the alloys causes the Gibbs free energy to be minimized and leads to the predominant formation of solid solutions with BCC, FCC or FCC + BCC structure. The phases formed on the basis of solid solutions are more stable than intermetallic compounds or other complex ordered structures [1,2].","PeriodicalId":87320,"journal":{"name":"Juniper online journal material science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48581378","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}

Consuming those stored energy reserves of the Glob resulted in quick depletion and their remains contaminate the planet. However, the renewable energy (RE) supply comes with a variety of benefits beyond the satisfaction of energy needs. It has a long-term cost advantage. Although the investment in RETs is still high as compared to the conventional fossil fuels usage, but according to the latest statistics it will be competitive even before 2025. Therefore, a renewable energy partnership shall be established between countries having good RE resources and countries with high electric energy consumption Europe, Middle East and North Africa. This paper aims to describe the scenario of the partnership between Europe, Middle East and North Africa (EUMENA) and experience their roles. This research shed the light on the main factors affecting electricity and water consumption, available resources & technology options, the advantages and obstacles facing MENA countries.","PeriodicalId":87320,"journal":{"name":"Juniper online journal material science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43649802","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}
