- creep mechanism;
- constant stress;
The creep properties at elevated temperatures of different grades of bauxite refractories with and without additions of K2O, MgO, etc., have been studied by torsion and compression test methods and correlated with phase composition and microstructure. The creep mechanism is discussed, based on analysis of parameters such as transient creep deceleration exponent (m), creep activation energy (AH) and stress exponent (n). It is concluded that creep behavior is mainly determined by microstructural characteristics and controlled by glass effect and crystal; effect.
