Solidification and Quenching Furnace (MSL-SQF)
MSL-SQF is primarily intended for metallurgical solidification research under steep temperature gradients, with the possibility of quenching the solidifying interface at the end of processing – by quickly displacing the cooling zone.
The maximum heater temperature of the SQF is about 1300 deg C with a thermal stability of 0.1 deg C. A maximum of 12 thermocouples can be integrated. A theoretical thermal gradient (along the sample) of 50-150 deg C cm-1 can be established. Translation speeds from 0.036 to 720 mm per hour can be applied. A maximum samples length of 275 mm for the current design.
The first experiments using the SQF insert are planned for 2010/11 on the ISS.
General features in both inserts are: rotating magnetic field, Seebeck and resistance measurements and ultrasound diagnostic system for the detection of the solid-liquid interface.
