摘要：

The effects of microstructural instability in 1 2Cr 1 2Mi 1 4V steel on the creep and creep rupture properties at engineering stresses are discussed. A working model describing the creep rate change with time is developed, based on the concept of a time-dependent friction stress" parameter. This model takes into account the changing material structure during extended component service life (≊100 000 h). The advantages of this approach over conventional applied creep rupture extrapolation techniques are outlined. © 1979."
