“…Inconel is a registered trademark of Special Metals Corporation for a family of austenitic nickel-chromium-based superalloys [ 10 ], with Inconel 625 and 718 alloys being most commonly used by the industry. The mechanical property and the processing for SLM directly formed nickel-based alloys have also been studied extensively [ 11 ]. The results show that the static tensile mechanical properties of 3D printed Inconel alloys are close to those of forged parts under the condition of material density, but the dynamic failure research of 3D printing materials is still limited.…”

Nickel-based alloy Inconel 625, produced by the selective laser melting method, was studied experimentally for its mechanical performance under strain rate loading using Hopkinson bars. Both compression and tensile tests were carried out, with the former also being conducted at 500 °C. The strain rate was in the range of 300 to 3500 s−1 at ambient temperature, and 1200 to 3500 s−1 at the elevated temperature, respectively, for compression tests, and 900 to 2400 s−1 for tensile tests. Results show that the alloy has a strong rate sensitivity with the dynamic yield stress at 3500 s−1, almost doubling the quasistatic value. The test results also show that, even though the temperature elevation leads to material softening, the strain rate effect is still evidential with the dynamic compressive yield stress at the rate 103 s−1 and 500 °C still being higher than the quasistatic one at ambient temperature. It is also observed that dynamic tensile strengths are generally higher than those of compressive ones at room temperature.

“…The results show that the grinding pressure has the greatest influence, followed by linear speed and feed speed. Ruzzi et al [14] used SiC grinding wheel to grind Inconel 625, and explored the influence law of grinding parameters on grinding force. Grinding direction has a great influence on grinding force, and the grinding force in the reverse grinding direction is small.…”

Key rotating parts such as integral blisks and blades of aero-engines are widely made of titanium alloys. Abrasive belt grinding is one of the effective methods to improve the surface integrity. However, the grinding process produces greater grinding force and higher Grinding temperature,which have an impact on surface quality. At present, the force-heat coupling relationship in the grinding process and its influence on surface quality have not been explored. In this paper, a titanium alloy belt experiment is carried out to detect the force and temperature in the grinding process, this paper explores the influence of the grinding process parameters on the grinding force and temperature, and analyzes the influence on surface integrity of the force and temperature in the grinding process. The results show that the decrease of the belt linear speed, the increase of the feed speed and the grinding depth leads to the increase of the grinding force, the decrease of the feed speed, the increase of the belt linear speed and the grinding depth cause the temperature to rise. The effect of grinding depth on grinding force and grinding temperature is the most significant. And High grinding force and grinding temperature will cause the surface quality to deteriorate and even more serious defects. However, when the maximum temperature of the grinding temperature field reaches above 120°C, the surface roughness of the workpiece decreases from 1.596μm to 1.093μm, and the height of the surface undulation is reduced from 32μm to 19μm. This paper provides a reference for improving the surface integrity of the grinding process.

“…Miao et al [5] conducted a comparative study on the grindability of superalloy GH4169, K403, directionally solidified superalloy DZ408 and single crystal superalloy DD6 during the creep-feeding grinding process, and analyzed the grinding force, grinding ratio, wear of wheel and surface integrity. Ruzzi et al [6] analyzed the influence of the several grinding parameters on surface integrity of nickel-based superalloy Inconel 625. Zhu et al [7] established the prediction model of surface roughness during grinding SiC p based on the cutting thickness of single abrasive conforms to the Rayleigh distribution, and obtained the optimized grinding parameters considering grinding efficiency and surface roughness.…”

Nickel-based single crystal superalloy has no grain boundary and excellent high-temperature performance. The traditional grinding mechanism of shearing and slipping along the polycrystalline material's grain boundary based on the theory of elastic-plastic deformation is not suitable for grinding single crystal parts. At present, there are few studies on microgrinding nickel-based single crystal superalloy. The grinding quality directly affects the workpiece's service life. To realize highquality and low-damage grinding nickel-based single crystal superalloy (001) crystal plane, this paper studied the surface roughness and the wear of the microgrinding tool. Firstly, it was assumed that the protrusion height of the electroplated abrasives on the grinding tool obeyed Rayleigh distribution. Based on the cutting state of abrasives, the prediction model of surface roughness of microgrinding nickel-based single crystal superalloy was established and verified by experiments. Secondly, the effect of grinding parameters on microgrinding surface roughness was analyzed through a single-factor experiment. Finally, the main wear forms, wear mechanism of grinding tool and the influence of grinding parameters on wear of grinding tool were analyzed. The results showed: although there was some error between the predicted value and the experimental value, the predicted value of the roughness and the experimental value had the same trend with the change of microgrinding parameters; with the increase in spindle speed (n g ) and the decrease in grinding depth (a p ), the surface roughness of microgrinding nickel-based single crystal superalloy showed a decreasing trend; with the increase in feeding rate (v w ), the surface roughness increased obviously; the wear of the grinding tool could be divided into five forms; the diameter of the microgrinding tool showed a trend of rapid reduction, then steady reduction, and finally rapid reduction under all grinding parameters. This study provided an important theoretical and practical reference for the manufacturing of nickel-based single crystal superalloy microparts.
