Evolution of the Solid Fraction at the Solidification of a 0.1 %C Steel
Journal Title: RECENT - Year 2012, Vol 13, Issue 36
Abstract
To achieve mathematical models and software for solidification simulation casted pieces it is necessary to know the fraction of the solid variation at solidification. In the case of the alloys form solid solution by solidification, this dependence is expressed with a better precision by a quadratic function. The quadratic function is determined on the on the equilibrium diagram. If you pursue to obtain simple mathematical models, the fraction of the solid variation at solidification is approximated by a linear function. In this case, the fraction of the solid variation at solidification is determined according to the liquidus and solidus temperature of the alloy. This paper illustrates how to determine these dependences for the steels with 0.1% C.
