Abstract

The Steel/Ni reinforced with 1.0-1.5 wt% TiC composite material was developed by compaction and sintering processes. Optical microscopy and Zeiss-Auriga field-emission scanning electron microscope (FE-SEM) revealed that the TiC particles segregated around the spherical Steel/Ni grains. Moreover, the 1.0 wt % TiC- Steel/Ni composite has the FCC Steel/Ni matrix while the 1.5 wt% TiC- Steel/Ni composite is comprised of the BCC Steel/Ni phase. The large TiC grains were found mostly on the 1.0 wt% TiC- Steel/Ni composite. Additionally, the 1.5 wt% TiC-Steel/Ni composite was composed of the ultrafine TiC grains that surrounded the FeNi spherical grains. The FCC Steel/Ni (1.0 wt% TiC)) composite has lower average hardness compared to the B2 Steel/Ni (1.5 wt% TiC) phase.
