“…The current study identified five wave numbers of the peaks (~260, 320, 464, 642 and 147 cm -1 ) similar to the frequencies of vibration corresponded to the six Raman active bands of the tetragonal Y-TZP [15] (Figure 4). According to some studies it is possible to identify the three main phases (monoclinic, tetragonal and cubic) because they exhibits changes in the zirconium oxide bond angles and lengths, indicating the phase transformation [15,19,22]. The main broad bands shown in our study were at ~260, 464, and 642 cm −1 (Figure 4).…”

“…They are due to tetragonal or cubic phases [15]. Different chemical stabilizers and crystal size probably caused few spectral variations at the tetragonal/cubic phases of this study (~260, 464, and 642 cm -1 ) [22,23] (Figure 4). The chemical stabilizers are almost the same for the three studied groups, except for some above described tracer elements for the EP (titanium dioxide and Clorium) and for the ST (aluminium trioxide).…”

“…The typical transformation zone sizes found experimentally are on the order of 20 µm or less [Casellas et al 2001]. The dilatant transformation will induce closure tractions on/along the crack faces.…”

“…La zona de análisis del haz incidente es circular con un diámetro de ∼10 μm. La proporción de fase m-ZrO 2 se calculó aplicando una ecuación calibrada para Y-TZP a partir de los resultados obtenidos mediante difracción de rayos X (8).…”
