This work investigates the effect of Cr on the FeTaTiW medium entropy alloy to form (CrFeTaTi)₇₀W₃₀ high entropy alloy, comparing the experimental production and characterization with the simulation (molecular dynamics and hybrid molecular dynamics-Monte Carlo) of the phases formed. The alloys were produced by mechanical alloying and sintered by spark plasma sintering. Both simulations have shown that a body-centered cubic structure is formed for both compositions. Monte Carlo simulation provides a more precise prediction of microstructural formation and element segregation. Microstructural examination of the consolidated material revealed the presence of a W-rich phase and a Ti–rich phase, consistent with the phase separation observed in the MC simulations. Moreover, X-ray diffraction analysis of the milled powder for FeTaTiW and (CrFeTaTi)₇₀W₃₀ confirmed the formation of a bcc (body-centered cubic)-type structure with a low fraction of intermetallic phases. Mechanical testing showed ductile behavior at 1000 °C where (CrFeTaTi)₇₀W₃₀ showed a stress magnitude almost double that of FeTaTiW. Additionally, the thermal diffusivity between 20 and 1000 °C of both alloys increases as the temperature rises. (CrFeTaTi)₇₀W₃₀ exhibits an increase from 3 to 5 mm²/s, while FeTaTiW increases from 4 to 9 mm²/s. Still, both system’s thermal diffusivity values are lower than those of CuCrZr and pure tungsten. Despite this, the study underscores the promising attributes of HEAs and highlights areas for further optimization to enhance its suitability for extreme conditions.\u0000</p></div>","PeriodicalId":592,"journal":{"name":"International Journal of Mechanical and Materials Engineering","volume":"20 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://jmsg.springeropen.com/counter/pdf/10.1186/s40712-025-00256-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kulkarni","doi":"10.1186/s40712-025-00260-5","DOIUrl":"10.1186/s40712-025-00260-5","url":null,"abstract":"<div><p>Acrylonitrile–Butadiene–Styrene (ABS) material known for its mechanical strengths and versatility in industrial applications deteriorates physically, chemically, and mechanically due to prolonged environmental exposure and loses its effectiveness over time, thus necessitating research into methods for rejuvenation and property restoration. This degradation impacts critical properties like impact resistance, tensile strength, and thermal stability, limiting ABS’s usability in manufacturing. This study explores advanced techniques for restoring aged ABS, including physical methods like reprocessing and thermal treatments, chemical restoration using solvents and additives, and mechanical enhancement through fibre or filler reinforcement. Each technique extends the lifespan of ABS materials, aligning with sustainable practices and the circular economy by reducing raw material consumption and minimising waste, enabling its reuse in industrial applications. Case studies on successful additive integration demonstrate the recycling process yielding 20% and 59% enhanced tensile and impact strength, improving material performance and durability after restoration. It was observed that the chain extenders in rABS boost the tensile and impact strength to 34.7 MPa and 6.3 kJ/m² from 20 MPa and 2.1 kJ/m² in aged ABS (almost 90% and 30% boost compared to virgin ABS). Studies also reflect that the effect of UV exposure reduces the impact and tensile strength by 50% and 25% after 6 and 12 months respectively. Stabilisers and plasticisers are observed to increase the service life and flexibility by 25% and 20% respectively in rABS. These findings demonstrate the significance of using mechanical and chemical stabilisers and mechanical reinforcement in ABS. The challenges include the cost-effectiveness, technical limitations, and regulatory concerns surrounding the use of restored ABS. Investing in biodegradable additives and smart materials for ABS restoration will drive sustainable innovation and enhance industrial circularity practices.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":592,"journal":{"name":"International Journal of Mechanical and Materials Engineering","volume":"20 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://jmsg.springeropen.com/counter/pdf/10.1186/s40712-025-00260-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143786593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
