Creeps are characterized as time-dependent permanent deformations that occur under constant stress at elevated temperatures. The material composition determines the onset of creep. For example, steel ...
Figure 1: Creep rate versus time curves of at 923 K and 140 MPa. Figure 2: Time to rupture of the 9Cr steels at 923 K and 140 MPa, as a function of carbon concentration. We have shown for martensitic ...
WHEN an annealed pure metal is loaded beyond the yield point, the deformation continues after the load is applied. The strain/time graph is called the creep curve. At constant stress Andrade 1 has ...
