Gradient hierarchical microstructure
WebThe gradient structure can be approximately regarded as consisting of many layers with systematic variation of microstructures and mechanical properties. The migrations of the elastic layer–plastic layer interfaces and the necking layer–stable layer interfaces present a challenge in studying many fundamental issues in the gradient structures. WebSep 19, 2014 · The gradient microstructure allows various plastic deformation mechanisms of largely different microstructures to be activated concurrently. This …

Web1 day ago · Graded and hierarchical microstructure is responsible for the evolution of graded micro-hardness and graded residual stress. The reduction in thickness of martensitic laths and increase in volume fraction of martensite lead to the increase of micro-hardness and strengthening effect with the gradient of 3.54 ± 0.16 HV/mm. WebApr 7, 2024 · As a proof-of-concept, we describe a novel hierarchical fibrous-grained (FG) microstructure in pure Ti. The specific fibrous microstructure with a preferred texture produces an intrinsically oriented microgrooved surface and a subnanometer hydrophilic anatase TiO 2 layer, ensuring fast osseointegration and remarkably bone-regeneration …
WebGradient metals have emerged as a class of hierarchical materials with tunable distribution of microstructures (4–8). As a result of the substantial strain gradients ( 9 – 13 ) intrinsic to these materials, gradient metals could be designed to exhibit an unusual combination of high strength and hardness, considerable ductility, and enhanced ...
