Fabrication of Textured Ti₃SiC₂ Ceramics by Slip Casting in a Magnetic Field and Pulsed Electric Current Sintering

Abstract

Plate-like Ti₃SiC₂ particles were prepared. Highly textured and dense Ti₃SiC₂ ceramics was successfully fabricated by slip casting plate-like particles in a strong magnetic field followed by pulsed electric current sintering at 1450℃under 80 MPa for 5min. 3 point bending strength and K_1C of the textured Ti₃SiC₂ ceramics were 812 MPa, 7.3 MPa・m^1/2, respectively. Compared to the Ti₃SiC₂ ceramics prepared by slip casting without magnetic field, the 3 point bending strength and K_1C of the textured Ti₃SiC₂ ceramics have been increased by factors of 1.05 and 1.22, respectively.
