Effects of sintering schedule to the characteristics of FeCrAl powder compacts formed at elevated temperature
This paper presents the outcomes of an experimental investigation on the effect of sintering schedule, i.e., holding time and temperature to the final properties of FeCrAl powder compacts prepared through uniaxial die compaction process at above room temperature. The feedstock was prepared by mec...

| description | This paper presents the outcomes of an experimental investigation on the effect of
sintering schedule, i.e., holding time and temperature to the final properties of FeCrAl powder
compacts prepared through uniaxial die compaction process at above room temperature. The
feedstock was prepared by mechanically mixing iron powder ASC 100.29 with chromium (22
wt%) and aluminium (11 wt%) for 30 min at room temperature. A cylindrical shape die was
filled with the powder mass and heated for one hour for uniform heating of the die assembly
together with the powder mass. Once the temperature reached to the setup temperature, i.e.,
150ºC, the powder mass was formed by applying an axial pressure of 425 MPa simultaneously
from upward and downward directions. The as-pressed green compacts were then cooled to
room temperature and subsequently sintered in argon gas fired furnace at a rate of 5ºC/min for
three different holding times, i.e., 30, 60, and 90 min at three different sintering temperatures,
i.e., 800, 900, and 1000ºC. The sintered samples were characterized for their density, electrical
resistivity, bending strength, and microstructure. The results revealed that the sample sintered
at 1000ºC for 90 min achieved the better characteristics. |
