Work pieces made of fine grained steel offer very high solidity at low material effort and are suitable for the production of crane vehicles and for weight reduction at shipbuilding.
The comparison of measured data that was obtained with thermocouples and optical measurement procedures shows a high accordance between simulation and experiment and therefore verifies the calculated results.

Experimental studies [4] suggest that the creep resistance can be modified not only by the addition or reduction of a certain alloying elements, but also by the grain size control in alloys.
Lee et al.[7] suggested that their data agreed with Garofalo’s model in which grain boundaries act simultaneously as both dislocation sources and barriers to dislocation movement.

The effects on microstructure of alloys include reduction of the grain size, control of columnar structure, formation of equiaxed grains, improvement of material homogeneity, and the uniform distribution of second phases.

Flow batteries
Like any type of electrochemical battery, flow batteries are based on reversible electrochemical reactions of oxidation and reduction (redox) reactions that occur in cells connected in series and/or parallel to obtain the desired voltage in the charging (electric energy storage) or discharging process (transfer of electricity to the electrical load) [2-4].
