Influence of Y2O3 contents on sintering and mechanical properties of B4C-Al2O3 multiphase ceramic composites

Effect of Boron Carbide on wear resistance of graphite containing Al7029 Based Hybrid Composites and its Dry Sliding Wear Characterization Through Experimental, Response Surface Method and ANOVA

“…The presence of graphite is indicated by an X-ray intensity peak of 26°, 54 0 . B4C particles have an X-ray intensity of 23°, 36 0 [23][24].…”

High‐strength TiB2‐B4C composite ceramics sintered by spark plasma sintering

“…To solve this intractable problem and eliminate these oxide films, MoSi 2 , Si 3 N 4 , B 4 C, SiC, C, Ni, Y 2 O 3 , Al 2 O 3 , ZrB 2 , and high-entropy alloys, et al have all used as additives or second phase substances to improve the sinterability and related properties of TiB 2 -based ceramics. [14][15][16][17][18][19][20][21][22][23][24][25] Ji et al 8 have used CoCrFeNiTiAl high-entropy alloy as sintering aid, which effectively reduced the sintering temperature and inhibited exaggerate grain growth of TiB 2 -based ceramics. Ahmadi et al 16 have reported that SiC can react with the oxide impurity TiO 2 on the surface of TiB 2 through chemical reaction, enhancing the sintering performance and the degree of densification effectively.…”

“…Ahmadi et al 16 have reported that SiC can react with the oxide impurity TiO 2 on the surface of TiB 2 through chemical reaction, enhancing the sintering performance and the degree of densification effectively. Lyu and Kim et al 19,23 have reported that Y 2 O 3 and Al 2 O 3 can successfully improve the sintering activity by reducing the activation energy of densification and increasing plastic flow mechanism in the sintering process of composite ceramics. SPS process was utilized by Germi et al to fabricate TiB 2 -based composites ceramics at 1900 • C under a pressure of 48 MPa for 7 min using Si 3 N 4 as the sintering aid and SiC as the reinforcement phase.…”
