“…Similar behaviour has been observed when bigger amounts of Y 2 Another interesting result derived from these analyses, is the radial segregation of Y 2 O 3 , which can reach concentrations of about two times higher in the centre than in the border of the rods, and it is independent of TiO 2 doping. The knowledge of the Y 2 O 3 distribution is necessary in order to know the ZrO 2 phase stabilization.…”

“…In case of studies on B 4 CNbB 2 eutectics Paderno et al 13) noted that indents made with a load of 150 g did not result in the formation of cracks, which is consistent with the findings of the present investigation (only small cracks were observed at loads of 300 and 500 g). In the present study, increasing the indentation load to 1 and 2 kg resulted in extensive crack growth, 25), 26) enabling the evaluation of K IC . The crack-microstructure interactions for eutectic composite with 35 mol.% NbB 2 are illustrated in Fig.…”

“…En los últimos años se ha vuelto la mirada hacia los óxidos cerámicos eutécticos, procesados por solidificación direccional, que constituyen una nueva familia de materiales con una resistencia mecánica superior a alta temperatura y una gran estabilidad térmica (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15). Estos materiales, al tener la composición eutéctica, solidifican como compuestos in-situ con una microestructura ordenada que puede variar desde organizaciones fibrosas o laminares a estructuras de colonias o redes interpenetradas.…”
