Degradation evaluation of Si 3 N 4 ceramic surface layer in contact with molten Al using microcantilever beam specimens

Measurement of mechanical properties of BaTiO₃ layer in multi-layered ceramic capacitor using a microcantilever beam specimen

“…Figure 4 shows the stressstrain curve obtained from the load-displacement curve of the microcantilever beam specimen, prepared in the BaTiO 3 layer of the MLCC. As reference, the stressstrain curve obtained from the loaddisplacement curve of Si 3 N 4 ceramics used in the previous study, 17) is also shown in Fig. 4.…”

Micro‐scale mechanical properties of surface layer in ion‐exchanged glass

“…[12][13][14][15][16][17][18][19][20][21] A load is applied at the tip of a microcantilever beam specimen to generate the bending stress on the top surface of the specimen. This method has been employed for investigating micro-scale mechanical performance of various inorganic materials including silicon nitride, [12][13][14] silicon carbide, 15 silicon, 16 zirconia, 17,18 alumina, 19 hydroxyapatite, 20 and high-entropy carbide. 21 The specimen thickness is typically two to three microns, while the case depth or the depth of the surface compression of ion-exchanged glass is usually several to several ten microns.…”

Deformation behaviors and fracture strength of β$\ubeta$‐Si3N4 single crystals

“…The microcantilever beam method is an effective technique to evaluate the local mechanical properties of ceramics under bending stress 14,22–25 . The advantage of this approach is the clarification of the whole deformation and fracture process until the final failure.…”

“…The microcantilever beam method is an effective technique to evaluate the local mechanical properties of ceramics under bending stress. 14,[22][23][24][25] The advantage of this approach is the clarification of the whole deformation and fracture process until the final failure. Tatami, et al 22 investigated the fracture strength of polycrystalline Si 3 N 4 ceramics as well as the fracture toughness of their grains and grain boundaries using microcantilever beam specimens obtained by direct sampling from bulk Si 3 N 4 ceramics through focused ion beam (FIB) technique.…”
