Method for Estimating the Internal Gas Pressure in the Pores of a Model Spherical Sample

Abstract—An analytical equation for the determination of the internal gas pressure in a pore is proposed. The equation is based on the solution of the problem of the theory of elasticity for the deformation of a spherical cavity situated at the center of a hollow sphere. This equation can be useful for the evaluation of the properties and structures of the products made by powder metallurgy methods and using additive technologies, as well as for the improvement of these technologies.
