Prediction of density in porous materials by x-ray techniques
Prediction of density in porous materials during mass production is one of the most important factors in industry. The existing methods for measuring density such as hydrostatic weighing and microscopical examinations have some limitations and inherent problems associated with them. Recently, processes based on radiography have emerged. This paper deals with the in situ prediction of density of porous materials using X-ray techniques. For this purpose, experiments were performed at various density levels of powder metallurgy compacts. In situ X-ray radiography was then carried out on samples. A correlation has been made between the film density of radiographic film and the surface density of the compacts. A mathematical relationship was derived between the absorbed x-ray, the film intensity and surface density. Comparison of values of Experimental data and mathematical relationship reveals discrepancies up to 3%.
