Reduction in Defect Content of ODS Alloys
Oxide dispersion strengthened (ODS) alloys prepared by mechanical alloying (MA) and subsequent consolidation are of increasing interest for potential application in components for use in power generation and furnace applications. After MA, canned alloy powders are usually subjected to a series of heat treatments. These heat treatments, particularly those at higher temperatures, last long enough...
متن کاملReduction in Defect Content in ODS Alloys
In order to develop FeCrAl-based ODS alloy tubing with the coarse, high aspect ratio, appropriately oriented grain structures likely to deliver enhanced high temperature (1100C) hoop creep strength compared to conventionally formed ODS alloy tubing, flow forming techniques were explored in a European funded programme. The evolution of microstructure in PM2000 alloy tubing formed by warm flow fo...
متن کاملIMPROVING THE WELDABILITY OF FeCrAl ALLOYS THROUGH TiC ADDITIONS
FeCrAl alloys were prepared with TiC additions to act as hydrogen traps and improve resistance to hydrogen cracking. Weldability results showed that alloys with up to 20 wt% Al and 11 wt% Cr could be prepared crack-free with relatively small TiC additions of ~ 4 wt%. Thermogravimetric analysis of Fe-10Al-5Cr corrosion coupons with and without TiC has shown that the corrosion resistance is not s...
متن کاملThe 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...
متن کاملEffect of nanoparticles addition on dissimilar joining of aluminum alloys by friction stir welding
The purpose of this study was to examine the effect of adding Nano particles such as Nano Carbon Tube during Friction Stir Welding (FSW) on dissimilar Al alloy joints. More specifically, both FSW and Friction Stir Processing (FSP) were performed simultaneously to investigate the effect of adding Nano particles on mechanical properties and microstructure of the weld zone for joining AA5754-H22 a...
