The dynamic differential scanning calorimetry (DSC) is a frequently used technique for analyzing steels and metals.
Linear heating and cooling experiments using DSC can phase transitions and their enthalpy and enable a solidus liquidus determination, which indicates at which temperature the sample melts and crystallizes.
The measurement shows the heating and cooling curve of a low-alloy steel sample, measured with a dynamic high-temperature differential calorimeter (HDSC PT 1600).
At 734 °C, the change in crystal structure and magnetic properties (ferromagnetic to paramagnetic) occurred.
The melting point can be seen at 1,411 °C.
The liquidus temperature was measured at 1,473 °C.
All peak values are reversible and can also be observed in the cooling segment (blue curve).
The crystallization range ranges from 1,454 °C to 1,436 °C and the phase transition phase transition to ferromagnetic takes place at a temperature of 637 °C.
