The presented measurement depicts the heating and cooling curve of a low-alloyed steel sample, conducted using the High Temperature Differential Scanning Calorimeter (HDSC PT 1600). Notably, at 734°C, a shift in crystal structure and magnetic properties occurred, transitioning from ferromagnetic to paramagnetic. The melting point of the sample is evident at 1411°C, with a liquidus temperature measured at 1473°C. All peaks displayed are reversible, observable during both the heating and cooling segments (as indicated by the blue curve). The crystallization range spans from 1454°C to 1436°C, and the phase transition to ferromagnetic state takes place at 637°C.
