Study on Friction and Wear Behavior of Inconel 625 Superalloy during Hot Extrusion

open access: yesAdvances 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 ...
