Sekundarni naslov: | Monitoring of the eutectic Pb-Sn alloy during directional solidification |
Sekundarni povzetek: | Microstructure evolution during solidification primarily depends on the velocity vSF and the temperature gradient GSF of the solidification front. It has a great influence on the mechanical and other properties of the cast alloys. It is therefore important to know the relationship between the influential solidification parameters and the evolving microstructure if the desired properties of solidified alloys are to be achieved. Thus, the measurement methods that allow online and nondestructive monitoring of these parameters represent a great challenge in the evolution of modern engineering materials. In this paper we discuss the usability of in-situ measurements of electrical resistance changes during the directional solidification for tracing the position and the velocity of the solidification front vSF. The electrical resistance changes were measured during directional solidification on a sample of the Pb-Sn eutectic alloy at different pulling velocities for displacing samples from the heating zone and at a constant temperature gradient of the furnace. The obtained values of the solidification front velocities vSF were subsequently compared with the values determined during the same solidification conditions by measuring the temperature changes with thermocouples, placed inside the sample. |
