Dynamic Characteristics Analysis of 3D Blade Tip Clearance for Turbine Blades with Typical Cracks
International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022 As well known, the crack is a typical fault of turbine blades, which is difficult to detect due to the weak fault features contained in the rotor vibration. Although some fault diagnosis methods based on blade tip timing (BTT) are proposed to detect blade cracks, the limited fault features can be extracted because the BTT signals contain only one ...

Study on Friction and Wear Behavior of Inconel 625 Superalloy during Hot Extrusion
Advances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020 Friction during the hot extrusion of Inconel 625 superalloy tubes causes severe wear of the mold and plays a decisive role in the quality of the workpieces. In this paper, a ball‐to‐disk method was utilized to investigate the tribological behavior of Inconel 625 using two different tribological pairs, i.e., GCr15 and Si3N4, at room and elevated ...
