Influence of Carbon Content on the Growth Angle of Steel Dendrites in a Flowing Melt.

Abstract

Using both experiments and numerical analysis, the influence of carbon content on deflection angle of dendrites has been studied. Experimental studies have been carried out using wide range of carbon contents. Numerical analysis has relied on finite-volume computer simulations. With the help of these techniques, it has been observed that the deflection angle increases with increasing carbon content. Dimensions of dendrite (dendrite tip radius and primary dendrite arm spacing) play an important role in distortion of solutal field around dendrite tip due to fluid flow and in eventually deflection of dendrites.
