Chromium hardening and Peierls mechanism for basal slip in sapphire (α-Al2O3) at temperatures between 900 and 1500 °C
(European Ceramic Society, 2007)
The plastic deformation of Cr3+-doped α-Al2O3 (ruby) with four distinct Cr concentrations has been studied at temperatures between 900 and 1500 °C. The mechanical tests indicate that the processes of dislocation multiplication ...
Correlation between microstructure and creep behavior in liquid-phase-sintered α-Silicon Carbide
(The American Ceramic Society, 2006)
The influence of increasing the sintering time from 1 to 7 h on the microstructure evolution and the mechanical properties at high temperature was studied in α-silicon carbide (α-SiC) sintered in argon atmosphere with ...
Effect of atmosphere and sintering time on the microstructure and mechanical properties at high temperatures of alpha-SiC sintered with liquid phase Y2O3-Al2O3
(Elsevier, 2006)
The influence that the atmosphere (N2 or Ar) and sintering time have on microstructure evolution in liquid-phase-sintered α-SiC (LPS-α-SiC) and on its mechanical properties at high temperature was investigated. The ...
