A Simple Calibration Method to Consider Plastic Deformation Influence on X-ray Elastic Constant Based on Peak Width Variation
Autor: Ewann Gautier, Pierre Faucheux, Bruno Levieil, Laurent Barrallier, Sylvain Calloch, Cédric Doudard
Publikováno v: Metals, Vol 14, Iss 1, p 62 (2024)
The sin²⁡ψ method is the general method for analyzing X-ray diffraction stress measurements. This method relies on the estimation of a parameter known as 12S2hkl, which is generally considered as a material constant. However, various studies have
