The starting point of the article is the operating principle of this specific type of combustion plant. This operating principle is based on the preheating of the combustor (combustion air) by taking over an important part of the enthalpy of its own combustion gases. Based on this principle, the recuperative burner of our own design has an energy efficiency that consists in reducing the specific consumption of fuel (natural gas) by about 25-35%. Also, the use of this specific type of combustion plant provides other functional advantages such as: a higher temperature in the hearth (due to a complete combustion), reduction of technological cycle times for the realization of various processes. The article also presents some functional parameters of a type-dimensional range of recuperative burners of our own design.","PeriodicalId":32608,"journal":{"name":"European Journal of Materials Science and Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41659613","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 application of aluminium foam in the vehicle industry is not a novelty. The crumple parts integrated with metal foam can be one of the better solutions to improve the impact energy-absorbing capacity of the vehicles. However, it is very important that the absorber can hold the mechanical behaviour under low and high-speed impact loads. The present study represents the mechanical behaviour and energy-absorbing efficiency of closed-cell aluminium foam investigated by different compression speeds. The investigation reveals the nexus of the impact speed and the amount of absorbed energy by the foam.","PeriodicalId":32608,"journal":{"name":"European Journal of Materials Science and Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41365529","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 American Gas Association (AGA) equation and Modified Colebrook-White equations were both used to estimate the capacity of the pipeline in its existing state, after internally coating and after injecting a drag reducing agent in the internally coated pipeline. By means of both AGA equations and Modified Colebrook–White equations, it was observed that Internal coating with surface roughness of 0.0045mm can increase the pipeline capacity (flowrate) by up to 22% for gas pipeline systems. Also, the synergetic use of a pipeline internal coating such as polyamide epoxy or solvent free epoxy and a Polyacrylamide drag reducing agent can increase the pipeline capacity (throughput) above 115.53% for GNGC gas pipeline systems. The analysis shows that synergetic use of internal coatings and drag reducers increases the capacity of gas pipelines and is economically justified with a typical payback period of three years.","PeriodicalId":32608,"journal":{"name":"European Journal of Materials Science and Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46364025","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}

Six alloys with a carbon equivalent value of 4.44 (hyper-eutectic composition) were used to evaluate the produced CADI, with antimony content ranging from 0.096 to 0.48 wt. %. The produced carbidic ductile irons (CDI) were heated to austenitic temperature of 910oC and held for 1 hour, then austempered at temperature of 325oC and held at different times (1-3 hours) to obtain carbidic austempered irons. Microstructural characterization was then carried out. The wear resistance was evaluated using a wear tester, it was noted that the wear resistance values of the CADI ranged from 2.35E8 cm-2 to 3.74E9 cm-2. The impact toughness of the CADI was determined using Charpy method, the results obtained ranged from 46.5 – 55J. It was observed that the as-cast CDI has graphite nodules, blocky carbides with a pearlitic matrix, the samples with antimony addition had granular carbides, the heat-treated samples had their matrix transformed to ausferrite while other structures remained unchanged. Sample with antimony content of 0.288 wt. % has the highest wear resistance value while sample with 0.096 wt. % has the best impact toughness value.","PeriodicalId":32608,"journal":{"name":"European Journal of Materials Science and Engineering","volume":"8 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41270140","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}

If it is not processed, it will pollute the environment and disrupt the life of various organisms. Tires and LDPE plastic waste can, however, be used as a mixture for making concrete bricks that contribute best in building infrastructure development by applying the principle of recycling. The addition of a mixture of used tire waste and LDPE plastic waste is useful for improving the physical properties and pavement content of concrete bricks and preventing the depletion of natural resources, achieving an Eco-Friendly program and making the cost of concrete bricks relatively cheaper. Concrete bricks are made with a mixture of used tire waste and LDPE plastic waste with 6 samples of different compositions. The quality of concrete brick is seen from three aspects, namely density, porosity and water absorption. The best quality of concrete bricks was obtained in sample 6 with a composition of 750 grams of used tire powder, 750 grams of LDPE plastic waste, 500 grams of coarse aggregate, 200 grams of cement and 750 ml of oil to obtain a density of 1129.252/1280, 864 kg/m³, 0.5% porosity, 0.434 % water absorption.
