The poor plasticity of metallic glasses (MGs) limits its applicability as engineering materials. Therefore, it is particularly important to find ways improve the glasses. In this study, effects pore diameter and B2–NiTi crystal on compressive deformation Ni50Ti50 MGs are studied by molecular dynamics simulation. results demonstrate that pores effectively inhibit rapidly stress reduction. Pore experiences pressure in direction load under compression process, which induce formation high shear...
Machine learning capabilities combined with in-situ TEM measurements on aluminum-carbon nanotube composites reveal a new deformation sequence of dislocation gliding and pinning, quiescent period, finally sudden release localized strain. We propose plastic mechanism operating three essential distinguishing characteristics: correlation spatially microstrustural defects the scale nanometers, barrier-activation process shear stress loading giving rise to strain response, transient response time...
Abstract Water-based anti-corrosion coatings, which are environmentally-friendly replacements for organic solvent-based do not perform well enough use in the most challenging corrosion environments. The high water absorption capacity of water-based latex films may reduce barrier performance by contributing to corrosive reactant/product transport. We seek understand coupled effects and ion transport hydrated films, propose mechanisms explaining these effects. Water immersed deionized (DI)...
Skin is the largest organ of many animals. Its protective function against hostile environments and predatorial attack makes high mechanical strength a vital characteristic. Here, we measured properties bass fish skins found that are highly ductile with rupture strain up to 30-40% 10-15 MPa. The exhibit strain-stiffening behavior. Stretching can effectively eliminate stress concentrations near pre-existing holes edge notches, suggesting damage tolerant. Our measurement determined...
