Comparative study on high temperature mechanical behavior in 3YTZP containing SWCNTs or MWCNTs
Miguel Castillo-Rodríguez, Antonio Muñoz, Arturo Domínguez-Rodríguez
Effects on mechanical properties of the presence of either single-walled carbon nanotubes (SWCNTs) or multi-walled carbon nanotubes (MWCNTs) in a 3YTZP matrix have been investigate…
Origin of the low precipitation hardening in magnesium alloys
C. M. Cepeda-Jiménez, M. Castillo-Rodríguez, M. T. Pérez-Prado
In this work electron backscattered diffraction (EBSD)-assisted slip trace analysis and transmission electron microscopy have been utilized to investigate the interaction of basal…
High temperature deformation mechanisms in monolithic 3YTZP and 3YTZP containing single wall carbon nanotubes
Miguel Castillo-Rodríguez, Antonio Muñoz, Arturo Domínguez-Rodríguez
Monolithic 3YTZP and 3YTZP containing 2.5 vol.% of single-walled carbon nanotubes (SWCNT) were fabricated by Spark Plasma Sintering (SPS) at 1250 C. Microstructural characterizatio…
Kink-pair mechanism and low temperature flow-stress behaviour of strontium titanate single crystals
M. Castillo-Rodríguez, W. Sigle
The mechanical behaviour of strontium titanate exhibits a remarkable behaviour at low temperature, in the so called regime A, where the flow stress experiences two different temper…
Analysis of a kink pair model applied to a peierls mechanism in basal and prism plane slips in sapphire deformed between 200C and 1800C
Miguel Castillo Rodríguez, Jacques Castaing, Antonio Muñoz Bernabé +2
A model based on dislocation glide controlled by the nucleation and propagation of kink pairs in a high Peierls stress crystal is revisited and modified to account for changes in d…
A critical assessment of the dislocation-driven model for superplasticity in yttria tetragonal zirconia polycrystals
A. Dominguez-Rodriguez, D. Gomez-Garcia, M. Castillo-Rodríguez
In this paper, the origin of the threshold stress in pure 3 mol %-yttria tetragonal zirconia polycrystals (YTZP) is analysed in detail. At this regard, the two explanations reporte…
