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 ...
In 1985, Pratt & Whitney (East Hartford, CT) commissioned an outside systems house to develop a proprietary computer-based creep system, ACTS (Automated Creep Test System). Written in Fortran and ...
