Abstract
Rapidly solidified Fe-30Cr-5Al alloy powders containing Ce up to 0.69 mass% produced by the Rotating-Water-Atomization Process were sintered and sheath-rolled. Rapidly solidified powders without Ce could be well sintered at temperatures more than 1673 K for time more than 3.6 ks. The grain size grew from 20 to 30 mm after annealing at 1673 K for 14.4 ks. The tensile strength of compacted Fe-30Cr-5Al powder was in the range from 350 to 450 MPa, and the elongation was in the range from 2 to 3%. The surface oxidation of particle was increased with the addition of Ce. However, it was suppressed in the Rotating-Water-Atomization under Ar atmosphere. The tensile strength of sheath-rolled Fe-30Cr-5Al-0.69Ce powder was 210 MPa. The tensile strength of compacted powders was superior to that of the as-cast material.
