Abstract
The solidification of complex nickel-based hardfacing alloys containin g large amounts of silicon, chromium and tungsten have been studied. T he transformation temperature are measured by differential thermal ana lysis. Quench interrupted directional solidification is employed to es tablish the solidification sequence. By means of quantitative electron probe microanalysis, the composition of the carbide (M(7)C(3) and M(6 )C) and boride phases have been determined The numerical simulation of the temperature during the solidification process allowed to explain some complex microstructures.
