Randomized trial validates crystallographic details in iron powder, suggesting a reliable analysis method.
Key Points
This research aims to validate the crystal structure of iron metal powder and showcase a method for extracting microstructural details from laboratory data.
Used powder X-ray diffraction to analyze iron powder
Extracted crystallographic and microstructural data over 36° to 95° angular range
Applied Williamson-Hall treatment for peak width and strain analysis.
Identified dominant reflections at 2θ = 44.850°, 65.218°, and 82.540°
Calculated average lattice constant of 2.859 Å, close to accepted value of 2.866 Å
Intensity analysis revealed discrepancies due to preferred orientation and peak selection.
