The Effect of Nickel Increasing and Aluminum Addition on Sulfidation Resistance of Fe-Ni-Cr Alloys (TECHNICAL NOTE)

In this research the effects of; increasing the amount of nickel and adding aluminum to create and prolong sulfidation resistance of Fe-Ni-Cr alloys have been investigated. Sulfidation tests were carried out at 1100°C in S/O bearing atmosphere. Prior to the tests, the specimens were annealed in argon at 1250°C for 8 hrs. Weight changes were measured and corroded deposits were analyzed byscannin...

COSMOS introduces an advanced web repository which allows teachers and students to search, retrieve, access educational content and re-use educational material for creating earning activities through a specifically designed web interface incorporating innovative technological s...

The Causes of Local Hardness Increasing in Powerplant Rotors and its Modification by Tempering (TECHNICAL NOTE)

Local hardness increasing on the surface of the power plant rotor may result in severe damages. One major solution for rapid repairing of the rotors is the adaptive tempering heat treatment. For this purpose, after identification of the damaged rotor, initial investigations and tests (such as visual inspection, chemical analysis, nondestructive hardness measurements and replica or on-site metal...
