In this research work, effect of electrode wire preheating on different responses including electrode wire melting rate, wire and plate melting efficiency, width of heat affected zone, microhardness, and corrosion rate of weld metal was studied. The experiments were carried out to accumulate the response data using the optimisation techniques. Then, the quadratic mathematical models were developed and checked the significance using the tests such as ANOVA, F-test and lack of fit. The preheat current is found to be the most contributing parameter, which efficiently enhanced the wire melting rate, wire melting efficiency and microhardness of weld metal whereas reduced the plate melting efficiency, heat affected zone (HAZ) width and corrosion rate. In addition, micrographs and micro-hardness results also confirmed the significant influence of preheat current.KEYWORDS: Weldingsteeloptimisationmicrostructuremicro-hardness Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.","PeriodicalId":45198,"journal":{"name":"Advances in Materials and Processing Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136136884","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}

Bagasse is agricultural waste, while chicken feathers can also be collected from poultry industry waste – both hold the potential to be used as fibre reinforcement in polymer matrix composite. The incorporation of both hybrid fibres together might have a synergistic effect on several properties. In the present research, composites at 5% fibre weight were prepared using a hot-press machine, altering the contribution of individual fibre, keeping bagasse and chicken feather at the ratio of 1:1, 3:1 and 1:3. Subsequently, tensile, flexural, impact, hardness and water absorption tests and thermo-gravimetric analysis were executed. Composite materials with a greater portion of chicken feathers (bagasse:chicken = 1:3) demonstrated superior mechanical properties, as well as better water absorption, thermal stability as compared to composite materials with a more significant proportion of bagasse fibre. To ensure excellent adhesion between polymer matrix and fibre, a significant factor for excellent reinforcement, chemical treatment with 5% NaOH was conducted on both fibres. Five per cent NaOH-treated hybrid fibre-reinforced composite outperformed untreated composite in impact strength, hardness, and water absorption.KEYWORDS: Bagasse and chicken feather fibrechemical treatmenthybrid compositemechanical propertiesTGA AcknowledgementsThe authors are thankful to the Department of Materials and Metallurgical Engineering, Bangladesh University of Engineering and Technology.

The polymerisation of vinylidene difluoride produces PVDF, which is a highly non-reactive thermoplastic fluoropolymer. Due to its higher flexibility and piezoelectric properties, fabrications of PVDF-based nanocomposites are much in demand today and have found lots of applications in next-generation sensing objects such as promising piezoelectric energy harvesters (nanogenerators), energy storage devices, sensor systems, and biomedical devices. In this work, a brief review of the nature and characteristics of PVDF-based polymers has been discussed.

Generally, gas turbines experience failure in their service on account of high thermal fatigue. In the present research, specimens of Inconel 718 superalloy are treated at two different temperatures 850℃ and 1000℃ (IHT1 & IHT2) with oil quenching, respectively. The specimens are studied with controlled strain amplitudes for different values 0.6%, 0.7% & 0.8% at room temperature and 800°C. It is noticed that the fatigue lifetimes of induction-hardened specimens are greater than those of untreated specimens at the above-mentioned strain amplitude values at room and elevated temperature, whereas the fatigue life of all the specimens reduces as strain amplitudes increase. Interestingly, the stress difference among the three strain amplitudes gradually decreases as the fatigue test progresses and induction-hardened specimens have cyclic softening behaviour as compared to untreated specimens’ cyclic hardening behaviour. Additionally, the mode of fracture for IN718 superalloys in the current study is entirely transgranular, as shown by the fracture surface observation using a scanning electron microscope (SEM).","PeriodicalId":45198,"journal":{"name":"Advances in Materials and Processing Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134989475","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}

Therefore, in this study, silicon nitride nanoparticles have been used to improve the hardness and wear resistance of the NiCrAlY alloy. The present research has examined the effect of different amounts of Si3N4 nanoparticles (1, 3, and 5 wt.%) on the structure and mechanical properties of NiCrAlY alloy. The samples were characterised by scanning electron microscopy, X-ray diffraction, and Vickers microhardness device. Initially, Si3N4 powders with 1, 3, and 5 wt% were mixed with NiCrAlY powder in a mechanical mill. Next, the powdered mixtures underwent spark plasma sintering (SPS) operations at 1100 °C for 6 min. The results of microhardness measurements showed that adding 1% Si3N4 to NiCrAlY caused the elevation of the hardness from 418 to 614 HV. Further, the sample indicated a wear rate of 1.42 × 10−5 (m3/N.m) at room temperature, under a loading force of 9.8 N, and a sliding length of 500 m. However, with an increase in the weight percentage of Si3N4 in the sample from 1 to 5 wt%, the hardness diminished from 614 to 543 HV.","PeriodicalId":45198,"journal":{"name":"Advances in Materials and Processing Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135938870","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}
