DENSIFICATION AND MECHANICAL PROPERTIES OF FEMN13-TiC COMPOSITES FABRICATED BY PULSED ELECTRIC CURRENT SINTERING PROCESS

Abstract

In the present work, FeMn13-40 wt.% TiC composite was fabricated by Pulsed Electric Current Sintering (PECS) process at different temperatures between 990 and 1020<sup>o</sup>C under a pressure of 60 MPa with a holding time of 5 min in the vacuum. Phases identification was done using the X-ray diffraction. The relative density, microstructure and hardness of the samples were characterized. The results showed that the relative density of FeMn13-TiC composite increased with the increase of sintering temperature. The highest relative density (96.19%) and the hardness (70.54 HRC) of the sample were achieved by PECS process, namely sintering at the temperature of 1020<sup>o</sup>C under the applied pressure of 60 MPa for 5 min.

Influence of Rare-Earth on the Microstructure and Mechanical Properties of High Manganese Steel Under Impact Load

“…As a result, the steel/the hardness property of the steel becomes strong, while the core retains the original microstructure maintain the toughness. This phenomenon of high manganese steel is called "deformation" [6][7][8][9][10][11][12][13][14][15]. Rare earth (RE) are rare elements in the earth, including 17 elements: Scandium, Yttrium, Lanthanum...…”
