Tensile creep properties of δ-Bi2O3

Research output: Contribution to journalArticlepeer-review


Isothermal tensile creep tests were performed on δ-Bi2O3 in the stress range of 0.1-0.8 MPa. A stress exponent of n = 1.3 was measured at 760°C in the stress range of 0.1-0.8 MPa or n = 1.0 in the range of 0.1-0.5 MPa. An average activation energy of Q = 165 kJ/mol was determined in the range of 680-760°C for a stress of 0.30 MPa. Creep rates before and after multiple thermal cycles about the allotropic range under stress were altered only slightly.
