High creep resistance
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.
