The effect of Cr variation on FCC/BCC phase formation AlCoCrxFeNi (x=0 - 1) is explored in the present work. Cr is known to be a BCC stabilizerand s-phase former. These phases were reported in AlCoCrFeNi HEAobtained through casting route. We adopted mechanical alloying andspark plasma sintering route, since it suppresses certain complexphases. It is observed that the Cr assists in FCC phase in com
Cr is known to be a BCC stabilizer in steels. In case of nanocrystalline AlCoCrFeNi high entropy alloys (HEA) synthesized by mechanical alloying (MA) and consolidated by spark plasma sintering (SPS), the systematic increase of Cr content from 0 mole to 1 mole supports and provides for the increase of Fe-Co-Cr rich FCC multicomponent phase. This increase in FCC phase fraction with increasing Cr con
AlxCoCrFeNi (x=0,0.3,0.6,1 mole) high entropy alloys with multiprincipal elements and varying Al content were synthesized through mechanical alloying. Elemental blends of CoCrFeNi, Al0.3CoCrFeNi, Al0.6CoCrFeNi and AlCoCrFeNi powders were subjected to high energy ball milling in Fritsch Pulverisette P-5 until the formation of solid solution. The as-milled HEA powders having grain sizes of around 10
One of the most anticipated properties of high entropy alloys (HEA) is excellent oxidation resistance. AlxCoCrFeNi (x=0,0.3,0.6,1 mole) HEAs were synthesized by mechanical alloying (MA) followed by consolidation through spark plasma sintering (SPS). Alloys with x = 0 and 0.3 show single phase FCC structure, whereas those with x = 0.6 and 1 have dual phases – FCC and BCC. Interestingly, synthesis t
DevOps has significantly improved the software development life-cycle by enabling fast, automated, and continuous integration and deployment (CI/CD). However, its application to Cyber-Physical Systems (CPS) presents unique challenges that require rethinking of traditional practices. DevOps in CPS becomes even more challenging when we consider sustainability, which is becoming increasingly importan
This article explores the potential for just knowledge production in Urban Living Labs (ULLs) by foregrounding epistemic justice. Drawing on autoethnographic and ethnographic methods, it examines how testimonial and hermeneutical injustices shape the formation, implementation, and dissemination phases of EU-funded, research-led ULLs.

One of the most anticipated properties of high entropy alloys (HEA) is excellent oxidation resistance. AlxCoCrFeNi (x=0,0.3,0.6,1 mole) HEAs were synthesized by arc melting route, followed by 4 remelting operations to ensure compositional homogenization. Alloys with x = 0 and 0.3 show single phase FCC structure and x = 1 have intricate BCC+B2 structure, whereas x = 0.6 have dual phases – FCC and B
High entropy alloys (HEA) containing Al and Cr have been observed to manifestimpressive dry air oxidation resistance. But the testing temperature attempted inthe previous works has been restricted up to 1050ºC. In the present work AlxCoCrFeNi HEAs (x=0,0.3,0.6,1 mole) synthesized by arc melting route have beensubjected to rigorous dry air oxidation test up to 1150ºC. The as cast HEAs withx=0 and x
The effect of the phase constitution of BCC/B2, FCC, Cr7C3 and their microstructural attributes are conspicuous on the hardness properties of AlCoCrFeNi HEAs [1]. The correlation of unsolicited C and O contaminant with process parameters (milling duration/rpm) and process control agent (PCA) categorically established that contamination increases with duration of mechanical alloying (MA) [2] . It i
BackgroundHematoma location may influence hematoma volume and risk of expansion, the strongest prognostic predictors in patients with intracerebral hemorrhage (ICH). This study aims to determine differences in imaging and clinical factors affecting survival in patients with lobar vs. deep ICH.MethodPatients with spontaneous supratentorial ICH residing in Skåne county registered in the Swedish Stro
Our current patterns of resource use have serious impact on the environment and are affecting our chances to future welfare. In this context, circular economy practices emerge as essential. Circular economy focuses on maximizing resource efficiency through reuse, repair, recycling, and product longevity—ultimately minimizing waste and reducing reliance on virgin materials.

Argument literacy – the ability to analyse and evaluate arguments in context – is essential in adult life. Yet, many struggle to distinguish opinions from reasoned claims, weak arguments from strong, and to understand how reasons support a claim. To address this, the Civic Argument Literacy Test (CALT) has been developed. It assesses nine argument literacy sub-skills using real-world-type examples
"Gabriel Karlssons utställning Kvarnämne förhåller sig till kvarnens malande som en bild för tanken och materialens ständiga förändring. Att utställningen visas i ett av rummen på Arnstedt Östra Karup som är en gammal vattendriven kvar och att Karlssons ateljé även den ligger i en gammal industrikvarn har blivit utgångspunkten för projektet.
