Mechanical metamaterials pave a way for designing and optimizing microstructure topology to achieve counterintuitive deformation including negative Poisson's ratio (NPR) thermal expansion (NTE). Previous studies were always limited single anomalous mechanical or deformation, but current applications high-precision optical equipment require their combination customized anisotropic parameters. This work develops programmable two-dimensional (2D) based on chiral antichiral structures...
Cylindrical fibers that are tens of micrometers long and ∼100 nm across synthesized from a diblock copolymer (see figure). The determination their persistence length other size parameters in organic solvents by light-scattering has been heroic. form liquid crystalline phases bromoform.
This work conducted tensile experiments from room temperature to 1100 °Con a new fourth-generation single crystal superalloys along [001]. The effect of on the properties and deformation mechanism alloy were investigated. Results showed that yield strength reached its peak value (1017MPa) at 850 °C. From 760 °C, occurrence stacking faults (SFs) was observed in γ matrix channel. γʹ phase. interface dislocation networks appeared 980 °C above. At temperature, sheared phase, which three types...
A surface-energy generator (SEG) using single-walled carbon nanotubes is demonstrated to harvest the surface energy of ethanol. The SEG can drive thermistors in a self-powered system. performance be significantly enhanced by Marangoni effect. These SEGs show advantages smaller inner resistance, no moving parts, and need for application an obvious external force.
Abstract Pro‐Environmental Behavior (PEB) of residents can greatly alleviate the threat environmental pollution to human living environment and promote sustainable development society. Cross‐cultural studies show that there are significant differences in PEB among countries with different cultural backgrounds. Even within same country or region, individual values not identical. So, various impact differently? To answer this question, paper investigates mechanism on how value affect...
Sluggish diffusion effect of high entropy alloy limits its bonding with other components in practical applications. In this paper, the surface mechanical attrition treatment (SMAT) strategy for performing joints (HEA) at a relative lower temperature is proposed. The EDS results demonstrate that distance Fe atoms increases significantly after SMAT since more gain boundaries are formed SMAT. Furthermore, method HEA/stainless steel joint can achieve useable strength 320 MPa 850 °C (∼0.63 Tm,...
This work introduced a facile method for fabricating heterostructures in medium Mn steel via direct warm rolling process. The heavy promoted the transformation of metastable austenite (∼12.2 vol%) into hard domain α' martensite, which formed heterogeneous microstructure with untransformed γ (soft domain). After 600 °C re-annealing, re-reversed to α + γ, and heterostructure disappeared. Compared homogeneous structure, exhibited synergistic enhancement strength-ductility (yield strength (YS):...
The majority of polymer-based materials demonstrate expansion upon absorbing water from the air. Mechanical metamaterials provide an interesting way to achieve unusual hygroscopic deformation. However, previous studies have only accommodated limited tunability negative by theoretical analysis but never involved other deformation modes. This work proposes modular reprogrammable 3D moisture-sensitive mechanical with switchable modes, which are built up multi-material 3D-printed bi-material...
Abstract The relationship between the corrosion resistance of cast duplex stainless steel welded joints and inclusions was investigated by metallographic characterization, electrochemical tests, in-situ scanning electron microscopy (SEM) combined with energy dispersive X-ray spectrometry (EDS) other methods. results showed that were main sites for pitting initiation in 2205 joints, MnS portion composite preferentially dissolved to form micro-pits, which triggered corrosion. In addition,...
