The welding procedures and welding parameters significantly affect the weldability and mechanical properties of aluminium alloys. In the current study, AA2219 alloy is welded using tungsten inert gas (TIG) and electron beam (EB) welding procedure to observe process parameters’ effect on tensile and corrosion properties. The experiments were planned by Box-Behneken design in which all the selected parameters were varied within a given range. Analysis of variance (ANOVA) was conducted, which established, that welding current is the major influencing parameter in TIG and EBW processes. The primary objective of the study is to develop the fitted mathematical model by integrating welding process parameters to predict the properties. The developed mathematical model was optimized by response surface methodology (RSM) to achieve the better ultimate tensile strength and corrosion resistance of AA2219 alloy upon welding by TIG, and EB welding process.","PeriodicalId":420098,"journal":{"name":"RECENT TRENDS IN MANUFACTURING TECHNOLOGIES, MATERIALS PROCESSING, AND TESTING","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128853613","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}

In this research the welding of martensite stainless steel 410 grade along with nickel based super alloy named Inconel 625 consisting of different variety of flux such as silicon dioxide, chromium trioxide, titanium dioxide with filler metal ERNiCrMo-3. The main purpose of this study is to find which flux serves the best in case of considered parameters such as hardness, toughness and the penetration of the weld. The results of this study were derived by performing tests in different machines like ultimate tensile test in order to find the tensile strength, Charpy impact apparatus to observe the toughness of the metal welded and Vickers hardness apparatus for finding the hardness of the welded metal. The microscopic appearances of the materials were examined with the help of optical microscopes. The final results show that Cr2O3 shows good penetration and better quality of join under the microscopic tests without any level defects. The metal fabricated with Cr2O3 flux shows more impact strength than the other fabricated materials.","PeriodicalId":420098,"journal":{"name":"RECENT TRENDS IN MANUFACTURING TECHNOLOGIES, MATERIALS PROCESSING, AND TESTING","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132729413","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}

Magnesium alloys are mixtures of magnesium with other metals (called an alloy), often zinc, manganese, silicon, copper, rare earths and zirconium. The magnesium alloys are having remarkable desirable properties like lightweight, low density (two thirds that of aluminium), good high-temperature mechanical properties. The addition of rare earth elements with the magnesium increases the strength and decreases the weld cracking and porosity during the casting process. Despite, the corrosion property of Magnesium alloy limits its applications. The corrosion behaviour of friction stir welded rare earth magnesium alloy ZE41 was investigated in present study. The friction stir welding was performed on 5mm thick specimens and under suitable welding conditions the defect free joints were made. The micro and macro structural analysis were performed. Mechanical tests have also been conducted to assess the tensile strength, joint efficiency, percentage of elongation and hardness of welded joints in various zones, i.e. weld nugget (WN), thermo-mechanical affected zone (TMAZ) and heat affected zone (HAZ). Micro Arc Oxidation (MAO) coating was done on the welded and base specimens to analyse the corrosion performance. The corrosion rates of coated (both base and welded) specimens were measured using salt spray test and the reduction in corrosion rates were identified after coating.","PeriodicalId":420098,"journal":{"name":"RECENT TRENDS IN MANUFACTURING TECHNOLOGIES, MATERIALS PROCESSING, AND TESTING","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126643388","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}

Two novel segments of this research are the analysis of the PLA material for the mechanical properties and the CFD analysis of the fan blade model to perform with high effectiveness. As the outcome of the research, it is observed that the tensile strength and elasticity of PLA materials manufactured through additive manufacturing increases with the increase in printing angle and thickness up to a threshold level. All the experimental results obtained are in the satisfactory range for an application involving fan blades. So the material can be suitable for the fabricating the fan blades without compromising the quality of the blades and application requirements. The CFD analysis have also been performed to design the fan blade and its twisting angle, thereby the maximum air flow can be obtained in all the directions.","PeriodicalId":420098,"journal":{"name":"RECENT TRENDS IN MANUFACTURING TECHNOLOGIES, MATERIALS PROCESSING, AND TESTING","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126348716","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 mechanical strength of AM parts can be improved by combining the properties of resins with polymers (Infiltration), which is applicable for open internal structures. Fused deposition modelling process is employed for fabricating, Solid and Lattice structures (Crisscross and Honeycomb). The fabricated lattice structures are subjected to pressureless resin infiltration process. Solid structures and Lattice structures (with & without infiltration) are tested for their compressive behaviour, ASTM D695. Compressive strength of lattice structures (with infiltration) are observed as 36.725 and 21.87 (Mpa), lattice structures (without infiltration) exhibits 27.65 and 19.60 (Mpa) and solid structures shown 11.7 Mpa. The results suggests that infilled lattice structures shows fine compressive behaviour compared to solid and lattice structures (without infiltration). The interface strength at the boundary region was observed better in Honeycomb type infiltration than crisscross type because of its increased sharp corners that providing interlocking phenomenon. The Scanning Electron Microscope images shown the good adhesive bonding in the interface boundary region of all the infiltrated samples which promises the usage of this technique in developing more hybrid composites.","PeriodicalId":420098,"journal":{"name":"RECENT TRENDS IN MANUFACTURING TECHNOLOGIES, MATERIALS PROCESSING, AND TESTING","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134557418","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}
