| Abstract | The programme will, in conjunction with a parallel NSF project at the University of Florida, identify the principal factors causing the formation of solidification defects in single crystal superalloy castings. The Imperial College project will focus on measuring the critical materials properties controlling the mechanisms that cause defects for alloy compositions and at temperatures appropriateto the melting range of advanced commercial and experimental SX superalloys. Particular attention will be paid to the role of refractory element additions (W, Re, Ru) and grain boundary modifiers (C, Hf) that have a profound effect on casting characteristics at low concentrations. The material properties are required required for quantification of numerical models of solidification and defect formation. Advanced measurement facilities at the National Physical Laboratory will be used for density, viscosity and surface tension characteriastion; techniques for measurement of liquid state solutediffusion will be refined within the programme. The measured constants will be incorporated in numerical models to simulate SX casting | |
