Microstructural analysis of steam oxidation of IN617 for use in ultra-supercritical steam plants [PDF]

open access: yesMaterials at High Temperatures, 2014
AbstractThe microstructural evolution of IN617 subjected to oxidising atmospheres of 100% steam, 50% steamyargon and air in the temperature range 700 – 750°C for exposures times up to 4000 h at atmospheric pressure has been investigated using a range of analytical electron microscopy techniques.

True Stability of Lubricants Determined Using the Ball‐on‐Disk Test

open access: yesAdvances in Tribology, Volume 2016, Issue 1, 2016., 2016
True stability of lubricants can be determined when there is minimum change in the contact area and also the intervention of wear debris in the contact zone. Here, we have used the ball‐on‐disk instrument with the migrating point contact, that is, relative motion between the ball and disk condition to fix the contact area and minimize the wear debris ...

Microstructural Changes in IN617 Superalloy during Creep at High Temperatures

open access: yesProcedia Engineering, 2014
AbstractIn an Ultra super critical power plant, it is considered to be necessary to use Ni-base super alloys with higher strength in addition to conventional heat-resistant steel. Out of various materials in the pipe line, one important alloy i.e. IN 617 super alloy is selected for the Ultra Supercritical power plant applications for operation.

Corrosion study of Ni-based alloy in ternary chloride salt for thermal storage application [PDF]

open access: yes, 2022
MgCl2/NaCl/KCl salt appeared as a high-potential heat transfer fluid for concentrated solar application, offering a wide operating range and low cost. Nevertheless, MgCl2 hydrates and atmosphere relative humidity are the limiting factors for a real scale
