“…These interactions affect the mechanical and thermal effects induced by the toolworkpiece contact during machining, which results in plastic deformation and microstructural changes in the machined layer [44]. The residual stress distributions influence the structural integrity and functional performance of the SDSS components, such as fatigue life, wear resistance, and corrosion resistance [45].…”

This work aimed to ascertain the corresponding influences of several PVD-coated cutting tools on the susceptibility of the machined surface of super duplex stainless steel (SDSS) to stress corrosion cracking. Coatings comprised of AlCrN, AlCrN/TiSiN, and AlTiN were applied to cemented carbide cutting tools using the PVD method; these were then used to turn the outer surface of the SDSS tube section. During the cutting process, the material presents the following combination of features: (i) a tendency for strain hardening, reflected in microstructural modifications and residual stresses of the machined surface and (ii) high temperatures in the cutting region, reducing the tool life. The goal of this work was to evaluate the surface integrity (work hardening and corrosion behaviour) of the SDSS obtained after the machining process (finish turning) with cemented carbide tools coated with three different PVD coatings.

“…The reason for this trend may be that when n is too low, the extrusion deformation between the cutting edge and the material is large, and the material and the tool are easy to bond, so the surface roughness is high. When n increases, the volume of removed material increases, the degree of strain hardening deteriorates, and the cutting resistance increases, resulting in an increase in surface roughness [29]. Because excessive n will lead to serious work hardening.…”

Micromilling (MM) is favored by the field of high-precision micro parts. However, the high plasticity of Inconel718 often poses a threat to MM, such as pits, humps and gullies, which affect the surface quality. In this study, the influence of ultrasonic vibration assisted micromilling (UVAMM) on surface quality is comprehensively analyzed by using the machining process of workpiece vibration, combined with cutting force, tool wear, surface morphology and corrosion resistance. The results show that, on the one hand, small amplitude plays a significant role in reducing cutting force and inhibiting tool wear. On the other hand, smaller speed, smaller feed rate and moderate amplitude will produce better surface morphology, which is a uniform and regular fish scale surface with lower surface roughness and fewer surface defects. Furthermore, the application of ultrasonic vibration also significantly improves the surface corrosion resistance of Inconel718. It is worth noting that the surface corrosion resistance does not completely depend on the surface roughness, but also has a close correlation with the surface morphology.

“…Pawade et al [ 8 ] proved the effects of cutting speed, cutting depth, feed rate and tool geometry parameters on residual stress by an experimental method; a residual compressive stress could be produced on a machined surface by adjusting cutting parameters and tool shape properly. Cheng et al [ 9 ] combined the cutting experiment results with finite element analysis methods, and found that the combination of cutting force and cutting heat produced high temperature and high pressure when acting on the rake face of the cutting tool, and inhomogeneous plastic deformation were introduced which led to residual stress. The effect of cutting force and temperature on residual stress in the milling process has been investigated by Jiang et al [ 10 ], and the results show that the cutting force plays a leading role in the residual stress, and the tangential residual stress was mainly caused by the tangential force and temperature.…”

In this paper, molecular dynamics simulations are performed to study the annealing process of γ-TiAl alloy with different parameters after introducing residual stress into prepressing. By mainly focusing on the dynamic evolution process of microdefects during annealing and the distribution of residual stress, the relationship between microstructure and residual stress is investigated. The results show that there is no phase transition during annealing, but atom distortion occurs with the change of temperature, and the average grain size slightly increases after annealing. There are some atom clusters in the grains, with a few point defects, and the point defect concentration increases with the rise in temperature, and vice versa; the higher the annealing temperature, the fewer the point defects in the grain after annealing. Due to the grain boundary volume shrinkage and and an increase in the plastic deformation of the grain boundaries during cooling, stress is released, and the average residual stress along Y and Z directions after annealing is less than the average residual stress after prepressing.
