Effects of Solute Redistribution on the Structure and Properties of Cast Alloys
Abstract
This report summarizes work on composite and alloy solidification presently conducted under the ONR contract and includes two papers on the simulation of heat flow and thermal stresses in continuous casting presented at the 'Conference on Computer Simulation for Materials Applications' in Gaithersburg, Md. in April 1976. A final element analysis of heat transfer in continuous casting is presented in the first paper. The steady state conditions of the solidification of a cylindrical alloy ingot are simulated. The analysis takes into account both radial and axial heat conduction and the variation of alloy properties with temperature. The analysis has the versatility to simulate any casting configuration as the program has the capability to treat any arbitrary boundary conditions. In the mold region, where an air gap generally forms, the position of gap formation, the size of the gap and the heat transfer through the gap by conduction and radiation are computed. Values predicted by the model are in close agreement with published laboratory and industrial data.
