Functionally Graded Material

In the field of materials science, functionally graded materials (FGMs) are characterised by progressive changes in composition and structure across volume that correlate to adjustments in the material's characteristics. Materials may be created for certain functions and applications. To create the functionally graded materials, several methods based on bulk (particulate processing), preform processing, layer processing, and melt processing are applied. FGM can be used in many different contexts. The idea is to create a composite material by changing the microstructure of one material while grading into another. The greatest qualities of both materials may therefore be combined in the material. To prevent corrosion, fatigue, fracture, and stress corrosion cracking, both strengths of the material may be employed, depending on the need for thermal, corrosive, malleable, or toughness. A power series may often be used to mimic the transition between the two materials. The idea of materials that can resist extremely high temperature gradients is of great interest to both the aviation and aerospace sector and the computer circuit industry. A metallic layer and a ceramic layer are often used to accomplish this. Functionally graded titanium/titanium boride test specimens underwent a quasi-static bending test, which was performed by the Air Vehicles Directorate. The test was compared to the finite element analysis (FEA), which used a quadrilateral mesh with individual structural and thermal parameters for each element.
