Abstract

CharaCteristiCs of the Growth of the DireCtionally soliDifieD fe-4.25% C euteCtiC alloyThe current work is dedicated to the mathematical description of a protrusion of the leading phase (cementite) over the wetting phase (austenite) observed during the author's experiments in previous articles. a cementite protrusion is confirmed in the directionally solidified Fe-4.25% c eutectic alloy. The protrusion is defined due to the mass balance fulfilment. a coordinate system is attached to the solid/liquid interface, which is moving with the constant growth rate v.
