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…

Microstructure and high temperature mechanical properties of liquid-phase-sintered $α$ -SiC with Y $_{2}$ O $_{3}$ -Al $_{2}$ O $_{3}$ additions

Miguel Castillo Rodríguez, Antonio Muñoz Bernabé, Arturo Domínguez Rodríguez

Samples of $α$ -SiC have been sintered with liquid phase (LPS) to 1950 $^{\circ}$ C, in atmosphere of argon and processing times between 1 and 7 hours. Using scanning electron microsco…

Chromium hardening and Peierls mechanism for basal slip in sapphire at temperatures between 900 and 1500 $^{\circ}$ C

Miguel Castillo Rodríguez, Antonio Muñoz Bernabé, Jacques Castaing +2

The plastic deformation of Cr3+ -doped a-Al2 O3 (ruby) with four distinct Cr concentrations has been studied at temperatures between 900 and 1500 $^{\circ}$ C. The mechanical tests in…
