Synchrotron Evaluation of Residual Stress in Palladium Alloy Substrate

Our study is dedicated to the development of a new high-energy stress evaluation method. The aim of this work is to improve some experimental techniques dedicated to the evaluation of residual stress at the surface and in the bulk of materials, by means of high-energy synchrotron measurements. This method has been applied to a machined palladium plate used in the manufacturing of dental prosthesis. Classical x-ray diffraction measurements are also carried out after chemical etching, to define the surface and in-depth stress of the sample, thus giving a reference to test the synchrotron radiation measurements.
