The macroscopic morphology of the aluminum alloy gradient plates prepared by the method first changed from burr to smooth, and vice versa. There is a different cross-section morphology of the prepared aluminum alloy gradient plates, however, the aluminum alloy plates are stirred and involved with each other, and the grains of the prepared plates are refined. The hardness of the upper and lower surfaces of the aluminum alloy gradient sheet decreases, whereas that of the upper surface of the side increases, and that of the middle and bottom sides also decreases. However, the hardness of the middle side of the sheet prepared with the rotation speed of the stirring tool at 800 rpm increases, but that of the bottom side still decreases. obtained through analysis that the performance of the aluminum alloy gradient sheet prepared at the stirring tool rotation speed of 500 rpm increases in equal proportion to achieve a good performance gradient change.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":" 90","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138961250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the cooling conditions of the moulded parts may contribute to changes in their shrinkage. the paper presents the results of determination of the melting enthalpy of a polypropylene. the melting enthalpy ∆ H m was determined by differential scanning calorimetry. it was found, that the value of the melting enthalpy depends on the physical conditions prevailing during the sample production process, such as the temperature of the liquid material, the cooling rate of the plastic (related to the mould temperature T m ) and the flow rate of the plastic in the mould. the degree of crystallinity of the obtained samples was also determined, which, depending on the measured enthalpy of fusion, influences the degree of structural order of the polymer. Standardized test samples were also analysed in terms of transversal shrinkage and longitudinal shrinkage. the shrinkage of the injection moulded parts results from the change of physical state of plastic during its solidification in the mould.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":"107 ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139172443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bending strength and flexural elasticity moduli were determined by following iSo 178:2019 standard specifications to assess the effect of two different technologies on the mechanical behavior of three-point bending specimens produced in three distinct build orientations (i.e., 0°, 45°, and 90°) relative to the printing platform. one-way aNoVa analysis, Tukey’s HSD, and Games-Howell tests are considered to assess the statistical variability of experimental data and compare the mean values of bending strength and flexural moduli. The testing results for the three orientations under question show notable differences and interesting similarities either in terms of strength or elasticity response for a significance p -level of 0.05.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":" March","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138960555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stir casting process is easy to use, involves low cost and is suitable for mass production compared to other manufacturing processes. an in-depth look at recently manufactured aluminium matrix composites and their impact on particle distribution, porosity, wettability, microstructure and mechanical properties of al matrix composites have all been studied in relation to stirring parameters. several significant concerns have been raised about the sample’s poor wettability, porosity and particle distribution. Mechanical, thermal, and tribological properties are frequently studied in conjunction with variations in reinforcement proportion but few studies on the effect of stirrer blade design and parameters such as stirrer shape, dimensions and position have been reported. To study the effect of stirrer blade design on particle distribution, computational fluid dynamics is used by researchers. reported multiphysics models were k - ε model and the k - ω model for simulation. it is necessary to analyse these models to determine which one best solves the real-time problem. stirrer design selection and analysis of its effect on particle distribution using simulation, while taking underlying physics into account, can be well-thought-out as a future area of research in the widely adopted stir casting field.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":"116 36","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138959044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
