Hydrogen's significance in contemporary society lies its remarkable energy density, yet integration into the worldwide grid presents a substantial challenge. Exposing materials to hydrogen environments leads degradation of mechanical properties, damage, and failure. While current approach for assessing hydrogen's impact on involves mainly multiscale modeling testing, there exists significant deficiency detecting intricate interactions between at nanoatomic scales under situ conditions. This...
Electrification of vehicles is the key to reduce greenhouse gas emissions meet new energy policies. New sources such as proton exchange membrane fuel cells (PEMFCs) have arisen one most sustainable solutions. Their performance depends on choice materials, bipolar plates (BPPs). Reduction in weight, volume, and costs are paramount importance enable commercialization popularization PEMFCs. In this context, aluminum emerges a promising candidate for BPPs, although its corrosion resistance...
The influence of test method factors (notch shape, square or angular, and pre-cracking method, by tapping onto pressing a razor blade) on the results obtained in plane strain fracture toughness according to standard ASTM D5045 using SENB specimens made commercial PMMA resin were investigated. Results analyzed quantitatively comparing KIc values qualitatively observing their effect Moiré fringes observed photoelasticity, showing that, at 95% significance level, are affected with most...
Fracture surface and microstructure of tensile samples taken from a centrifugally cast 20Cr32Ni + Nb alloy tube were investigated in the 'as cast' state after being submitted to isochronal aging at temperatures between 670 °C 820 for 200 h. The results show that main crack path is interdendritic macroscopic scale, but fracture characterized by dimples microscale all samples, suggesting micromechanism does not change, spite large ductility loss observed aged (fracture elongation, ε¯f≈0.16,...
In ball-cratering wear tests, two abrasive modes are commonly observed, grooving abrasion and rolling abrasion, which act in distinct areas. Observing this tendency, the aim of article is to discuss characterization an intermediate condition, superposition observed. This phenomenon referred as microrolling due following particular characteristic: was found on abrasion. Additionally, a defined sliding distance range normal force range, qualitatively observed be proportional inversely force.
Thermoplastic polyethylene has been increasingly used in important structural applications, e.g., the production of pipelines for water and natural gas distribution systems, leading to growing interest characterization material's fracture toughness. By virtue its high ductility at room temperature, elastic-plastic toughness concepts are most convenient this purpose. In work, a systematic study about suitability Essential Work Fracture (EWF) test protocol medium density (MDPE) resin designed...
The abundance of iron and aluminum raw materials is often quoted as a strategic advantage aluminides against other competing (not only stainless steels, but also nickel titanium aluminides). These materials, however, are not abundant in the form ores earth's crust, scrap produced extensive technological activity associated with these base metals. present work reports results two prospective experiments designed for obtaining exclusively from readily available (aluminum cans, carbon steel...
