{"title":"Experimental Investigation on Wear Behavior of AA4032 Reinforced Nano Si3N4 Using Novel Encapsulate Stir Casting Technique","authors":"Hemachandran Bharath, L. Natrayan, Agaram Sundaram","doi":"10.17756/nwj.2023-s3-075","DOIUrl":"https://doi.org/10.17756/nwj.2023-s3-075","url":null,"abstract":"This research delved into the intricate comparison between the wear behavior of as-cast AA4032, and a composite blend enriched with 10% nano Si 3 N 4 . This composite wasn’t constructed through conventional methods but utilized a sophisticated encapsulating technique, underpinning its distinctiveness. Creating samples for the composite and the as-cast alloy relied on a combination of stir-casting and the aforementioned encapsulating method. The research was bifurcated into two primary groups to ensure clarity and distinction. Group 1 championed the as-cast AA4032, presenting it in its pure, unaltered state. In contrast, group 2 featured a meticulous blend of AA4032 alloy and 10% nano Si 3 N 4 , presenting a reinforced composite. To maintain a gold standard in producing these samples, the globally recognized ASTM E92 standards were diligently followed. The true mettle of these samples was then tested using the pin-on-disc apparatus, a trusted method in evaluating wear behaviour. Each group consisted of 20 carefully crafted samples, leading to 40 samples for the entire research. The rationale behind choosing this sample size was driven by the G-power analysis, which stood at 80%, combined with an α value of 0.05 for each set. The findings were nothing short of revelatory. The composite bolstered by the 10% nano Si 3 N 4 manifested wear resistance properties that surpassed its as-cast AA4032 counterpart by a staggering 58%. Further strengthening these findings was the t-test’s statistical analysis, which underscored a marked difference between the two groups. With a compelling p-value of 0.00 (indicative of a significant distinction when p < 0.05), the wear variance between group 1 and group 2 came to the fore. Given the constraints and parameters of this exhaustive research, one clear insight emerged: adding 10% nano Si 3 N 4 to the AA4032 alloy dramatically augments its wear resistance, pointing towards the vast potential of this composite in industrial applications.","PeriodicalId":36802,"journal":{"name":"NanoWorld Journal","volume":"96 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139318751","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}

This amalgamation was achieved through an innovative encapsulation method, and the outcome was juxtaposed against the hardness of the as-cast AA8176. A distinctive encapsulation stir-casting technique was the methodology chosen for the fabrication of the samples in both groups. Group 1 was the product of an amal-gamation between nano graphene (comprising 10% of the total) and AA8176. Conversely, group 2 exclusively utilized AA8176. Adherence to the ASTM E92 standards was paramount in the preparation of these samples. The hardness of these prepared samples was then discerned by employing a Vickers hardness apparatus. Each of the two groups had a set of 20 meticulously prepared samples. The computational procedure to determine the sample size was anchored in a G-power of 80%, with an α value set at 0.05, resulting in a total sample size of 40. The results revealed that the hardness apex was achieved with the material infused with 10% graphene, registering a hardness uptick of 25% in comparison to the as-cast AA8176. The t-test, a statistical analytical tool, confirmed a marked variance in the hardness mean between the two groups, registering a significant p-value of 0.00 (p < 0.05). Drawing from the evidence and data presented within the contours of this research, one can conclusively infer that the integration of 10% nano graphene into the AA8176 composite markedly elevates its hardness.","PeriodicalId":36802,"journal":{"name":"NanoWorld Journal","volume":"206 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139318721","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 cement industry is a significant contributor to carbon emissions and is second only to water in terms of global usage. India’s construction industry is one of the largest consumers of natural resources. As part of efforts to reduce the environmental impact of concrete production, researchers have explored the potential of gold mine waste as a substitute for fine aggregates in concrete. In particular, the tailings from the Kolar Gold Field in Karnataka, India, have been investigated. The study assessed the mechanical characteristics of concrete that substituted various amounts of gold mine waste for fine aggregates. After curing for 7, 14, and 28 days, the concrete’s compression and split tensile strengths were evaluated. The results indicated that the strength of the concrete increased with increasing replacement of fine aggregates with gold mine waste up to 25%.

The rice manufacturing industry produces a large amount of RHA waste, which is an ecologically beneficial pozzo-lanic substance and low-cost. Cement mortar is mixed with a 1:3 cement/sand ratio, with nano zirconia as a replacement for cement in different content (1%, 2%, 3%, 4%, and 5% by the weight of cement) and RHA as a replacement for fine aggregate in various amounts (10%, 20%, 30%, 40%, 50%, 60%, and 70% by the weight of fine aggregate).

Among these waste materials, granite powder waste originating from stone processing units has emerged as a major challenge due to its detrimental impact on soil and water resources. Conventional disposal methods have contributed to soil degradation and environmental contamination, necessitating the search for sustainable alternatives for waste management. In this context, the utilization of red soil blended with granite powder waste presents a promising avenue for sustainable construction practices. This study delves into the nano-level characterization of this composite material and investigates its potential applications. Advanced characterization techniques, particularly scanning electron microscopy (SEM) and energy-dispersive X-ray analysis (EDX), were used to analyze the behavior of red soil mixed with different percentages of granite powder waste. The results highlight the mix with 30% granite powder waste as a particularly noteworthy composition, showcasing superior interlocking properties. The microstructure analysis at the nanoscale revealed the formation of clusters, leading to enhanced cohesion between particles and improved interlocking behavior. These findings demonstrate the potential of this soil-waste composite for sustainable soil improvement and geotechnical applications in construction. By understanding the nano-level interactions be-tween red soil and granite powder waste, this study paves the way for innovative and environmentally conscious approaches to soil stabilization, promoting the efficient utilization of waste materials in construction projects. The research concludes with insights into future directions, focusing on long-term stability studies and potential environmental impacts. The application of nano-additives in soil stabilization opens up new possibilities for sustainable development and resource efficiency.","PeriodicalId":36802,"journal":{"name":"NanoWorld Journal","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139319951","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}
