Diffraction-based residual stress mapping of a stress frame of gray iron via vibratory stress relief method. Frontiers in Materials, 9, 859342. doi:10.3389/fmats.2022.859342en_US
dc.description.abstractThe role of residual stress is critical, particularly for machine tools demanding accuracy below 1 µm. Although minor stresses are subjected to a tiny area, the applied force can cause devastating distortions on the precision components at this length scale. In this research, we systematically investigated the residual stress in a stress frame of the gray iron used in machine tools using synchrotron X-ray and neutron sources. Through the combination of these techniques, the residual stresses on the surface, inside the bulk, and in average were presented. Comprehensive analysis results shed light on the vibratory stress relief technique, which reduced the residual stresses and stabilized them, even materials undergoing cycling heating. Although compressive stresses are not effectively reduced, this technique is useful in improving the mechanical stability of the materials in machine tools. © 2022 Chen, Huang, Chiu, Reid, Wu, Paradowska, Lam, Wu, Lee, Lu, Chen, Lin and Weng.
