Data from "A novel synthesis pathway for oxide dispersion strengthened Fe–Cr alloys enabled by ultrasonic atomization"

Desired composition of the alloy under investigation: Fe-14Cr-0.4Ti-0.5Y (in wt.%) / Fe-15Cr-0.5-0.3Y (at.%).

AA = as-atomized powder (ultrasonic atomization)

HT = heat-treated powder (1100 °C/1 h)

FAST = field assisted sintered (1130 °C/5 min/24 kN)
