Going step by step is important even under time constraints. Define key requirements: 1) Max operating temperature; 2) mechanical properties (strength, creep); 3) chemical properties (corrosion/oxidation stability in operating environment; 4)thermal conductivity, CTE; 5)manufacturability (source/fabrication); 6) other properties, if needed (optical, magnetic); 7) safety issues. Search database, use AI tools to narrow down to few viable material choice: Metals/ Alloys/Ceramics/polymers/composites. Do simulation (finite element, molecular dynamics, DFT, ) to fine tune device design parameters (size, shape, composition). Build test structures, conduct stress test, narrow down choices. Integrate into device, evaluate functional performance.

First Check the stability of material Then go for their phase identification and crystal structure After that go for their morphological analysis then apply several physical characterization techniques such a VSM Dielectric FTIR Raman..etc.

Define requirements, check material charts, leverage past experience, consult experts, prioritize safety, and ensure availability.

One thing I’ve found helpful is that I must pick up the project that focused on specific missions that costs do not play a critical role in. If the society of scientists accepted me in their environment as a tiny association, I would play a vital role in reaching the destination instead of marketing. Exploring a novel thing is making a new roadmap in unfamiliar lands. Expand, do not play.

Just add to what others have mentioned. In spite of the application, choice of materials and properties, design considerations and fabrication, one should also be mindful of cost implication.
