Web1 de jul. de 2024 · The steady creep rates of the HEC are much smaller than those of the transition metal carbides reported in the literature for similar creep conditions, [ 21, 22 ]. For NbC, the creep rate at 1500 °C/40 MPa is 1.59 × 10 −8 /s, much higher than that of HEC crept at much higher stresses or temperatures. Web11 de abr. de 2024 · In general, the creep strain is achieved by the competitive result of work hardening and dynamic recovery. Thus, a high creep resistance can be fulfilled under the condition of a strong work hardening effect provided by the strong entanglement of high-density dislocations in 1Mn samples [[29], [30], [31]].
