steel research international, EarlyView.The phase transformation behavior of a hypoeutectoid steel is studied in comparison with alloys containing higher concentrations of tramp elements, simulating high recycling rates. The examination of microstructures reveals that the tramp elements facilitate the formation of displacive phases along with retained austenite.

Steel: Past the Crossroads [PDF]
, 1983 [Excerpt] A majority of the 154,532 steelworkers who are presently laid off will never go back to work. They will be shut out of the steel industry because the steel companies have a new game plan.

Using Thermodynamics and Microstructure to Mitigate Overfitting in Pellet Reduction Models
steel research international, EarlyView.A in time and space discretized, thermodynamically sound model for direct reduction of iron oxide pellets is described. The number of fitting parameters is drastically reduced compared to existing models. Nevertheless, fitting kinetic parameters based on conversion degree data alone leads to overfitting, which can be mitigated by correlating the ...

steel research international, EarlyView.A CALculation of PHAse Diagrams thermodynamic modeling for Fe–Sn–C system is carried out. The model and the developed database can be used to calculate phase diagrams and thermodynamic properties of this system over wide temperature/composition range, and a part of a larger thermodynamic database for steel and alloy system, and effectively used to ...

NEW TENDENCIES IN MARKETING [PDF]
, 2011 BACKGROUND: Vasospasm is the major cause of morbidity and mortality after aneurysmal subarachnoid hemorrhage. It is well known that the vasoreactivity decreases with advancing age, but it is not well investigated in a large patient cohort whether, as a ...
