...Patricia M. Dardati; Luis A. Godoy; Diego J. Celentano This paper presents a new micro-macro approach for the thermo-microstructural behavior of the solidification process of an eutectic ductile cast iron. The thermal balance is written at a macroscopic level and can take into account both...

...X. Richard Zhang; Xianfan Xu This work developes a finite element model to compute thermal and thermomechanical phenomena during pulsed laser induced melting and solidification. The essential elements of the model are handling of stress and strain release during melting and their retrieval during...

...Faruk Yigit Previous theoretical models of pure metal solidification on a patterned mold surface neglected either the thermal capacitance of the solidifying shell material (which is equivalent to assume that thermal diffusivity is infinitely large) or interfacial coupling between the thermal...

... in which, at any given time, the spatial temperature distributions are represented in infinite series. The effect of the solid, liquid Stefan numbers and the unsteady boundary temperature variation is investigated. The results showed a retrograde motion of the solidification front for large liquid Stefan...

...L. G. Hector,, Jr.; J. A. Howarth; O. Richmond, Mem. ASME; W.-S. Kim A theoretical model that predicts the time and position of gap nucleation along the metal-shell interface during solidification of a pure metal on a sinusoidal mold surface is presented. The ratio of the mold surface amplitude...

...F. Yigit; L. G. Hector,, Jr. A theoretical model of the gap nucleation process during pure metal solidification on a deformable mold of finite thickness is presented. Both surfaces of the mold follow a sinusoidal lay for which the ratio of the amplitude to the wavelength, or aspect ratio, is much...

...F. Yigit; L. G. Hector,, Jr. In this second part, we examine the contact pressure ratio, P tr , at the lowest points of the upper mold surface troughs in a directional solidification process using the theoretical methodology developed in Part I. Since there is ample experimental evidence...
