In situ TEM experiments reveal the crystalline-to-amorphous phase transformation in an ultrafine-grained Cantor alloy.
It is of significance, but still remains a key challenge, to simultaneously enhance the strength and damping capacities in metals, as these two properties are often mutually exclusive. Here, we provide multidesign strategy for defeating such conflict by developing Mg-NiTi composite with bicontinuous interpenetrating-phase architecture through infiltration magnesium melt into three-dimensionally printed Nitinol scaffold. The exhibits unique combination mechanical improved strengths at ambient...
Making replacements for the human body similar to natural tissue offers significant advantages but remains a key challenge. This is pertinent synthetic dental materials, which rarely reproduce actual properties of teeth and generally demonstrate relatively poor damage tolerance. Here new bioinspired ceramic-polymer composites with nacre-mimetic lamellar brick-and-mortar architectures are reported, resemble, respectively, dentin enamel in hardness, stiffness, strength exhibit exceptional...
Abstract Biological materials exhibit anisotropic characteristics because of the anisometric nature their constituents and preferred alignment within interfacial matrices. The regulation structural orientations is basis for material designs in may offer inspiration man‐made materials. Here, how orientation anisotropy are designed into biological to achieve diverse functionalities revisited. dependencies differing mechanical properties introduced based on a 2D composite model with wood bone...
Grain boundary (GB) segregation has a substantial effect on the microstructure evolution and properties of polycrystalline alloys. The mechanism nanoscale at various GBs in multicomponent alloys is great challenge to reveal remains elusive so far. To address this issue, we studied GB representative equiatomic FeMnNiCoCr high-entropy alloy (HEA) aged 450 \ifmmode^\circ\else\textdegree\fi{}C. By combining transmission Kikuchi diffraction, atom probe tomography analysis density-based...
Increasing the fatigue strengths of high-strength materials, especially their endurance limits is essentially challenging. The nanocrystalline (NC) Cu and Cu–Al alloys processed by high-pressure torsion were prominently enhanced with a decrease in stacking fault energy. This remarkable escalation can be attributed not only to significantly increased tensile macro-scale, but also improved microstructure stability reduced strain localization within shear bands microscale. Owing limitation...
Titanium-magnesium (Ti–Mg) composites have attracted increasing interest recently due to their partial degradability and excellent mechanical properties, which offers a new promise for medical bone implant repair materials. Here we present Ti–Mg composite fabricated by pressureless infiltration of pure Mg melt into the 3D-printed Ti scaffold. The spatially controllable distribution phase structure topology was achieved 3D printing technology. electrochemical corrosion in vitro degradation...
Abstract Despite the extensive investigation on structure of natural biological materials, insufficient attention has been paid to structural imperfections by which mechanical properties synthetic materials are dominated. In this study, bivalve Saxidomus purpuratus shell systematically characterized quantitatively multiple length scales from millimeter sub-nanometer. It is revealed that hierarchical intrinsically involved in crossed-lamellar despite its periodically packed platelets....
Abstract As important lightweight structural materials, cast aluminum alloys have been largely used in the transportation and aerospace industries. In general, Al–Si-based comprise more than 90% of all castings due to their excellent castability corrosion resistance. However, even though various reinforcements introduced, strength these is not that high, which severely limits use for certain high-performance applications. Here, we report on a new strategy technology reinforce Al–Si increase...
