In the industrial cutting of alloy GH4169, high cutting force and temperature have always been important factors affecting machining quality and efficiency. In view of this, this study aims to improve the cutting performance of the alloy GH4169, and special attention was given to the changes in cutting force and temperatures under different parameters with ceramic turning experiments, and the optimal cutting parameters were determined based on orthogonal experimental design. The work findings indicate that the resultant force initially increased and then declined with the increase of cutting speed, while it showed increasing trend with the increased of both feed rate and depth of cut. Meanwhile, cutting temperature was positive related to both the cutting speed, feed rate and depth of cut. Based on the range analysis and variance analysis, the depth of cut had the greatest impact on the resultant force and cutting temperature, followed by cutting speed and feed rate, and only the depth of cut significantly affected the changes in resultant force and cutting temperature. Finally, an optimal cutting condition with the lowest resultant force and temperature was determined, where cutting speed is 150 m/min, feed rate is 0.05 mm/r, and depth of cut is 0.1 mm. It is proposed to be used in the industrial machining of alloys GH4169 for the grater product quality and benefits.

“…19,20 For this purpose, vast literature is dedicated to the selection of the most suitable process parameters able to optimize the static 21 and the fatigue strength. 17,21,22 To this regard, the design of components that undergo cyclic loads should be carefully considered, as prediction of fatigue life and industrial safety depends on many different factors, such as loading conditions, the manufacturing processes of the starting materials, 23 the crystalline structure of the component, 24 the finishing condition, 25,26 and the presence of defects. As an example, the presence of interstitial elements or non-metallic inclusions in the base materials to be welded can represent preferential crack initiation sites during cyclic loading conditions.…”

This study investigates the fatigue corrosion behavior of direct drive friction welded ASTM A105 and AISI 304L steels joints. Axial fatigue tests were carried out at a stress ratio of R = 0.1 in air and different corrosive environments using a 3D printed environmental test cell. The samples were tested in 3.5%wt NaCl aqueous solution at free corrosion potential (Ecorr) and other two polarization conditions (−0.85 and −1.30 V vs. Ag/AgCl) with the objective to highlight the influence of the cathodic protection and the influence of evolved hydrogen on the fatigue behavior. Fracture analyses were conducted through optical and electron microscopy to identify the possible causes of failure nucleation and the different damage mechanisms dictated by the aggressive environment. Principal results quantify the detrimental effect of the corrosive environment and the positive role played by the cathodic protection. Moreover, a clear differentiation in the failure site and mechanism was observed for the different corrosion fatigue conditions.

“…Torres et al [11] found that micro-cracks formed on the surface of AISI 4340 steel during shot peening would have an impact on the initiation location of cracks. Wu et al [12] studied the influence of different polishing methods on the rotary bending fatigue life of nickel-based Alloy GH4169. Klein et al [13] showed that the surface morphology had a significant impact on the cyclic deformation behavior of TWIP steel under high cycle fatigue.…”

In the field of materials science, the fabrication of a material with severe surface plastic deformation and a good surface state is an issue encountered in the development of counterbalanced gradient materials. For this paper, AISI 4340 steel was first processed with abrasive water jet peening (AWJP) and then with ultrasonic surface rolling (USRE) to obtain a good surface state while maintaining large plastic deformation. The AISI 4340 steel composite surface was therefore modified, and the surface integrity and cycle fatigue performance were analyzed. The results show that the plastic deformation layer of the modified composite surface of the 4340 steel was 310 µm from the surface of the sample, the grain size 40 µm from the surface layer was refined to 70 nm, and the maximum surface roughness Ra is 0.06. The fatigue limit of the modified composite surfaces obtained by the tensile fatigue test was 595.7 MPa, which was 85.7 MPa higher than the 510 MPa fatigue limit of the unmodified matrix, indicating that the method of composite surface modification can produce a deep deformation layer while maintaining good surface conditions. The results show that work hardening caused by a composite surface treatment is the most important factor for improving the fatigue performance of materials.
