Design and production of ceramic laminates with high mechanical reliability

Relationship between residual stresses and mechanical behavior in ceramic composites

“…A slight improvement in can be seen in tape casting samples when compared to slip casting samples with the same Y-TZP content. The determined values in this study using SELNB method are acceptable, compared with those reported in literature for similar compositions and determined by other conventional methods such as single edge notch bending test (SENB) [50,185] or bending of the specimens with Vickers indentations [185,186]. For example, Tuan et al [50] obtained fracture toughness values of ~5.0 MPa·m 1/2 for A-5YTZP materials with similar microstructure.…”

SiC-based multilayered composites containing short carbon fibres obtained by tape casting

“…Several multilayer ceramics have been investigated in the past [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]; a wide range of materials have been studied, SiC [4][5][6][7][8][9][10], Si 3 N 4 [11,12], Al 2 O 3 and its composites [2,3,[13][14][15] or other compositions [16][17][18]. Pure ceramics [2][3][4][5][6][7][8][9][10][11][12], alternating layers structures [13][14][15][16]…”

“…Pure ceramics [2][3][4][5][6][7][8][9][10][11][12], alternating layers structures [13][14][15][16][17][18][19][20][21][22] sometimes containing composites [17][18] have been considered, and two main methods have been used to enhance toughness over conventional ceramics, namely the introduction of weak interfaces [4][5][6][7]13,14] or the presence of residual stresses [16,[18][19][20][21][22].…”

Effect of nano-metal particles on the fracture toughness of metal–ceramic composite

“…In order to solve this problem, many approaches have been proposed to enhance the fracture toughness of ceramics. There are three main toughening techniques of ceramics: (i) particle dispersion toughening [2,3], (ii) multilayer toughening [4,5], and (iii) phase transformation toughening [6]. One of the particle dispersion toughening methods is based on the concept of mixing brittle ceramics with ductile metals [7][8][9].The ductile metals can lead to toughening of the composite through two distinct ways [10].…”
