Summary: The study investigates the distribution of residual stresses in Ti6Al4V alloy during ultrasonic vibration assisted turning (UVAT). Experimental and finite element simulations were conducted to analyze the effects of vibrating and cutting parameters on residual stress profiles. The simulation results were validated with experimental data, and the influence of thermo-mechanical loading on residual stress distribution and subsurface layer of machined component was analyzed.

Summary: This study deposited ternary nitrides with carbon atoms into tool steel using different techniques, and found that the introduction of carbon significantly reduced residual stresses. The compressive residual stresses in multilayer coatings increased with the addition of TiAlN interlayers, and the wear coefficients of HiPIMS coatings were notably lower than DCMS coatings.

Summary: The intragranular strains and microstructure within recrystallizing grains in single phase pure iron have been studied using synchrotron micro-diffraction. Residual elastic strains of up to 1-2 x 10(-3) were observed in the recrystallizing grains, contradicting common knowledge. The local strain variations within individual grains can be similar in magnitude to those between different grains. The effects of processing and microstructural parameters on the development of local residual elastic strains and microstructure have been quantified.

Summary: Residual stresses are important for tuning the properties of thin films and nanomultilayers, but their measurement and evaluation are challenging. This study investigated the relationship between crystal orientation and residual stresses in Cu/Mo and Cu/Nb nanomultilayers and proposed a modified method for measuring residual stresses in materials with strong fiber texture.

Summary: This study investigates ultrasonic elliptical vibration-assisted turning (UEAT) through experimental study and three-dimensional finite element simulation. The study also compares this process with ultrasonic-assisted turning (UAT) and conventional turning (CT). The effects of elliptical vibrations on cutting forces, friction coefficient, and residual stresses are examined using both experimental tests and finite element simulations. The results show that applying elliptical vibrations in UEAT can significantly increase the compressive nature of machining residual stresses.

Summary: This paper presents an updated method for predicting turning-induced residual stress based on a two-scale approach, which is more accurate and accessible than previous 3D hybrid methods. The new global hybrid strategy defines thermo-mechanical shapes more accurately using local 2D orthogonal cutting models and allows for easier calibration of equivalent thermo-mechanical loadings. This model provides results considering the effective machined surface topography and has been shown to predict residual stress state induced by turning operations more accurately within a shorter time frame.

Summary: The study evaluated the influence of turning parameters on residual stresses in AISI 1045 steel bars, finding that feed rate and cutting speed had a major impact on residual stress distributions. The tool nose radius affected surface residual stresses, while the rake angle did not significantly change it. Samples could be divided into two residual stress groups based on surface finishing quality.

Summary: This paper aims to provide spatially resolved distributions of residual stresses using X-ray diffraction measurements and a spatial deconvolution technique. The method is first applied to reconstruct residual stresses in two reference cases with strong agreement between the reference stress profiles and the reconstructed ones. Experimental X-ray diffraction measurements also show a good agreement between the local stress profile reconstructed from the measurements and that predicted numerically.

Summary: This study investigates the effect of laser scan strategy on the three-dimensional residual stress state of L-PBF metallic components. High-energy X-ray diffraction was used to measure residual stress in Ti-6Al-4V bridge components built with different scanning patterns. The observed residual stresses were found to be large, around 1/2 to 3/4 of the yield strength, with higher stresses near the edges of components built with island scan strategies.
