On the t → m martensitic transformation in Ce–Y-TZP ceramics

Zirconia nanoparticles: a martensitic phase transition at low temperature

“…We find three real eigenvectors, which form an orthogonal set. The deformation matrix representing the Bain strain, which converts the tetragonal zirconia lattice to the monoclinic zirconia lattice is given by: After the magnitudes and directions of the principal axes on the lattice deformation have been obtained from the Equation (2), the locus of initial directions of all vectors, which are not changed in length by the lattice deformation, known as the initial Bain cone, can be obtained, as well [21].…”

“…where (BCA) is the Bain [21] correspondence matrix between the initial phase (A) and the final phase B, (AC 0 B) is the transpose of (BCA), (B*GB) and (A*GA) are the metrics for the final and initial phases, respectively, A* and B* are the reciprocal lattices for the initial and final phases, respectively.…”

Application of response surface methodology (RSM) for optimization of the sintering process of preparation calcia partially stabilized zirconia (CaO-PSZ) using natural baddeleyite

“…It is possible to stabilize the ZrO 2 in the tetragonal and/or cubic forms at room temperature [7], by adding different stabilizers, such as, MgO [8][9][10][11], CaO [12], Y 2 O 3 [13][14][15], CeO 2 [16,17], Al 2 O 3 [18] and even a combination of them [19,20]. Different quantities of stabilizer can cause zirconia to stabilize in different phase composition.…”

Study of Thermoelastic Martensitic Transformations Using a Phase-Field Model

“…[15] Therefore, Mn-rich Mn-Cu alloys are taken as an example in the current work to study thermoelastic forward and reverse MTs using a phasefield model. The lattice parameters of Mn-rich Mn-Cu alloys, c/a, of the fct martensite gradually decrease when temperature is decreased.…”
