A computational multiscale method is proposed to simulate coupled, nonequilibrium thermomechanical processes. This multiscale framework couples together thermomechanical equations at the coarse scale with nonequilibrium molecular dynamics at the fine scale. The novel concept of distributed coarse scale thermostats enables subsets of fine scale atoms to be attached to different coarse scale node...

  Abstract   Recovery and recrystallization phenomena and effects of microalloying elements on these phenomena are of great importance in designing thermomechanical processes of microalloyed steels. Thus, understanding and modeling of microstructure evolution during hot deformation leads to optimize the processing conditions and to improve the product properties.   In this study, finite element...

The conventional tubing supplied to oilfields with low aggressive environments: pCO 2 up 0.3 atm and pH S 0.005 often shows signs of pitting carbon dioxide corrosion after operation. To solve the problem, a new sparingly alloyed steel 25KhGB was developed for K grade increased set performance characteristics obtained thermomechanical treatment.
