Dislocation dissociation and stacking-fault energy calculation in strontium titanate
Castillo-Rodríguez, Miguel; Sigle, W. (Elsevier, 2010)The dislocation microstructure of strontium titanate plastically deformed below room temperature shows dipolar configurations of a〈1 1 0〉 screw dislocations. The dipole height is so small that dipole annihilation is expected. ... -
The kink-pair mechanism and low-temperature flow-stress behaviour of strontium titanate single crystals
Castillo-Rodríguez, Miguel; Sigle, W. (Elsevier, 2011)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 temperature dependences separated by a noticeably ...
