The phrase "a graded structure" is correct and usable in written English.
It can be used in contexts where you are discussing a system or framework that is organized in levels or degrees of complexity or importance.
Example: "The curriculum is designed with a graded structure to ensure that students build their knowledge progressively."
Alternatives: "a hierarchical framework" or "a tiered system".
A graded structure of W8Cu1/W7Cu2/W6Cu3/Cu6W3/Cu8W1 is therefore suggested theoretically.
The foams obtained in this study had a graded structure with an overall porosity of 20 60%.
For the processing conditions used the clad material presents a graded structure consisting of 5 layers with different microstructures, resulting from the prevalent material solidification path.
The synthesized coating shows a graded structure composed of various amounts of molybdenum and tungsten disilicide as well as an aluminoborosilica top layer.
This study designed and implemented a compound interface, comprising a series of metal, metal nitride, and metal carbonitride interlayers deposited in a graded structure, between the DLC (a metal-doped a-C H) film a-C H2 steel substrates.
A periodontal membrane with a graded structure allows tailoring of the layer properties to design a material system that will retain its physical, chemical and mechanical characteristics for a period long enough to optimize periodontal regeneration.
Dental enamel is the outermost layer of a tooth crown consisting of a hierarchical and graded structure.
We then proved that this model was applicable to the graded structure of a PVC/PMMA graded blend.
It is suggested that the "dots-in-a-graded-well" structure might serve as a better active medium than the "dots-in-a-well" structure.
Unlike existing uniform or mono-gradient structures, this paper introduces a novel dual functionally graded structure with changing both foam density and wall thickness along the transverse direction, namely transverse functionally graded foam-filled and functionally graded wall thickness (FGF-FGT) structures.
On the FeB + α-Fe coated samples the wear mechanism is mainly oxidative and the coating totally wears out without spalling as a consequence of its graded structure, which succeeds in both improving the adhesion of the coating to the substrate and reducing the residual stress at the coating substrate interface.
