초록
The time-dependent plastic deformation (i.e., ‘creep’) in Li2O-SnO2-B2O3-P2O5 ceramic glasses was probed by nanoindentation creep tests at room temperature. We paid attention to the ‘stress exponent (n)’ as a major indicator of the room-temperature creep behavior of the ceramic glasses. The estimated stress exponents for steady-state creep are mostly in the range 5~15 and did not significantly change with the indentation peak load.
Abstract
The time-dependent plastic deformation (i.e., ‘creep’) in Li2O-SnO2-B2O3-P2O5 ceramic glasses was probed by nanoindentation creep tests at room temperature. We paid attention to the ‘stress exponent (n)’ as a major indicator of the room-temperature creep behavior of the ceramic glasses. The estimated stress exponents for steady-state creep are mostly in the range 5~15 and did not significantly change with the indentation peak load.
