In this paper Cobalt-Chromium-Molybdenum (Co-Cr-Mo) specimens produced by Selective Laser Melting (SLM) for biomedical field were studied. particular, fatigue tests carried out comparing as-built condition with Hot Isostatic Pressing (HIP) and a heat treatment under vacuum condition. The influence on microstructure properties was investigated plain V-notched geometry. Both HIP had effects the internal defects, which resulted in an enhancement of quasi-static properties. Lastly, notch...
Reinforcement of polymers by the addition particles filler is a complex phenomenon that depends mainly on hydrodynamic effect and interplay between polymer, filler, interfacial region. Mineral fillers are usually adopted as low-cost extenders due to their lower cost. In this study, influence waste material such electric arc furnace steel slag assessed for Nitrile-Butadiene Rubber following experimental procedures analytical calculations traditional fillers. It was found content affects...
This study investigates the impact of post-processing techniques on fatigue behaviour specimens in Ti6Al4V made by laser powder bed fusion (LPBF) for relevant applications, such as motorsport. Despite LPBF advantages terms complex design and weight reduction, challenges reduced performance persist. Therefore, application treatments can play a critical role. In addition to traditional sandblasting (SB), three conditions were investigated enhance mechanical properties under quasi-static...
Carbon black (CB) is the most widely used reinforcing filler for rubber. Nowadays there are several concerns regarding this traditional petroleum-based filler: on one side its environmental footprint enormous and production process no more sustainable other price increases annually. For these reasons, alternative fillers being studied. In present research main waste of steel industry, namely slag from electric arc furnace (EAF), investigated as non-conventional a nitrile butadiene rubber...
The COVID-19 pandemic exposed critical gaps in healthcare infrastructure, particularly the lack of effective isolation anterooms for managing infectious diseases. This study presents TrainerWall, a cost-effective, portable anteroom designed rapid deployment both high-resource and resource-limited settings. TrainerWall features modular, self-supporting structure with antimicrobial materials, integrated sanitization, adaptable dimensions, ensuring seamless integration into environments without...
To evaluate the introduction of selective laser melting (SLM) for serial application, some features directly related to components safety and performances are be deeply analyzed. this purpose, present article applies three different types heat treatment on Ti6Al4V as‐received samples produced by SLM: 1) annealing stress relieving, 2) solubilization super‐β transus, 3) sub‐β transus followed a tempering. Then, microstructures, mechanical resistance, residual stresses, corrosion resistance...
Additive manufacturing (AM) could be used to reduce the production times of prototypes; however, further research is required address metals structural parts. To obtain correct properties, some relevant factors considered are build volume, shape factor, and need for specific heat treatments. This study aims evaluate reliability AM prototypes applied at a new powertrain system developed vehicle emissions. Firstly, it was investigated mechanical behavior, microstructure, effect sample size...
The automotive industry is undergoing a rapid evolution to meet today’s challenges; therefore, continuous innovation and product development are needed. Validation tests on prototypes play crucial role in moving new components into industrial production. There also pressing need for faster prototyping processes. In this context, sand casting (RSC), based additive manufacturing technology, offers promising solution quick production of molds. While technology already employed the industry,...
The auditory function of 75 children affected by homozygous beta0-thalassemia, managed with a low transfusion scheme and treated irregularly doses desferrioxamine, controls were examined. In 12 patients mild bilateral conductive hearing impairment due to bony hypertrophy and/or adenoid was found. 43 cases moderate monolateral or sensory-neural loss at high frequencies recruitment phenomenon observed. Ferritin levels determined in randomly chosen group these (14) without heaing (11). the...
Abstract This work shows an innovative application for electric arc furnace (EAF) slag: its use as a filler nitrile butadiene rubber (NBR). Composites with various EAF slag contents were tested. It was found that the polymer matrix significantly reduces leaching of (determined according to standard CEN-EN 12457-2) incorporated in NBR. The processability characteristics determined by rheometric curves highlight accelerates crosslinking kinetics, reducing production cycle time. Mechanical...
Serum ferritin, liver iron stores, and histology were studied in 38 children with thalassaemia major who being treated by regular blood transfusions. There was no correlation between serum ferritin levels either the number of transfusions or amount deposited liver. However, for a given level higher patients chronic hepatitis (including aggressive persistent forms) than those hepatic siderosis only. We conclude that reflects tissue deposits regularly transfused thalassaemic patients, only...
A deep knowledge of material properties is fundamental to obtain high‐performance medical implants realized with CoCrMo alloy manufactured by selective laser melting (SLM), even more so when considering that heat treatments (HTs) are often necessary refine the microstructure, eliminate residual stress, and improve mechanical properties. To this aim, herein, SLM samples produced in six different treatment conditions: as built (AB), four vacuum HTs, hot isostatic pressing (HIP). Modifications...
Over the years, natural resources conservation and waste management have become increasingly important globally, leading to promotion of systemic approaches that integrate different processes by sharing materials, energy, services. Recycling reuse materials also an area increasing interest. This study investigates potential use ladle furnace (LF) slag, a product steel industry, as non-conventional filler for rubber compounds. LF slag is produced during refinement stage steelmaking process...
The European steel industry produces about 70 million tons/year of by the electric arc furnace (EAF). slag consists 15% weight produced steel, thus from perspective circular economy, it has a high potential as co-product. This research aims to assess an innovative reuse EAF filler in different polymer matrixes: thermoplastic (polypropylene), thermosetting (epoxy resin), elastomeric (nitrile butadiene rubber), and recycled end life rubber tire. A comparison between neat filled with certain...
