Strengthening of Fe-Cr-Al-Y Oxidation Resistant Alloys.
Abstract
An investigation of oxide dispersion strengthening of oxidation resistant FeCrAlY alloys was conducted using both coarse and fine metal powder approaches. The most successful method involved preoxidizing and extruding Fe-25Cr-4Al-1Y (2541) coarse atomized powders. A detailed thermomechanical processing (TMP) study of this material showed that 2000F tensile and stress rupture properties varied widely with rolling-heat treating schedules. Yield and tensile strengths at 2000F were from 1 to 4.5 times the values for conventional alloy 2541 and 2000F rupture stress at constant Larsen Miller parameter number were from 1 to more than 5.3 times the values for conventional alloy 2541 depending on TMP schedule used.
