The Characterization of a Gas-Atomized Ferritic Steel Powder Pre-alloyed with 6 Wt Pct Aluminum

In this paper, the microstructure of a gas-atomized steel powder pre-alloyed with aluminum (11.4 Cr, 10.0 Co, 5.7 Al, 5.1 Ni and Fe in wt pct) is characterized. The as-atomized powder contains NiAl-rich precipitates and most of the particles are covered with a thin (
