Abstract

Abstract: In order to prevent and mitigate the harm of fretting damage to nuclear reactor steam generator tube, the effect of grain size on fretting wear behavior of Inconel 690 alloy was investigated systemically. Fretting wear test was conducted to study fretting wear characteristics of the Inconel 690 alloy, and microstructure, hardness and worn scars characterization of the alloy at different solution temperature were observed by means of OM, Vickers hardness tester, SEM, EDS and LSCM. The results indicate that the grain size increases with the increase of solution temperature, whereas the hardness decreases. In the gross slip regime, the friction factor hardly changes with the variation of grain size and hardness, which is 0.48. The grain size of the Inconel 690 alloy with the value of 112 μm, while the ratio of hardness of SS304 alloy to the Inconel 690 alloy with the value of 260∶176.4 are proved to favor for the alloy to acquire the lowest level of wear volume. With different grain size and hardness, the main mechanism of fretting wear for the Inconel 690 alloy are delamination wear, abrasive wear and adhesive wear.

Key words: Inconel 690 alloy, grain size, hardness, friction factor, fretting wear
