TA 12.13 - Thermal Analysis
Basis Thermal Analysis TA 12.13
The new hardware specially developed for the Thermal Analysis TA 12.13 enables very accurate measurements and was designed for daily use in the rough foundry environment. Various laboratory and field tests of different Al alloys were microscopically evaluated by means of specially prepared polished sections and chemical treatment of the polished surfaces for grain boundary determination. The grain size was determined by measuring approx. 100 grains per section in two axes and then calculating the average value. The dimensionless grain refinement number is based on the grain size table of the American ASTM standard. Thus, the TA 12.13 anticipates the time-consuming procedure of a polished specimen preparation and enables a standardised comparison of specimens.

Thermocouple, crucible and protection tube
Thermocouple
The sensor stand was specially developed for the Thermal Analysis and contains a permanent thermocouple for direct measurement. The thermocouples comply with class 1 (NiCr-Ni) and their deviations are tested by mk. These can be stored in the monitoring unit and therefore taken into account during test work.
Crucible
The durable stainless-steel crucible has a capacity of 90 g for molten Al.
Protection tube
Thermal Analysis samples along with the embedded stainless-steel tube can be returned directly to the melt where they dissolve without leaving any troublesome ceramic or sand residues.
