HDSC PT 1600 – Low alloyed steel – DSC

Steel sample – Phase transition / melting / solidus-liquidus

Differential Scanning Calorimetry (DSC) is a widely employed technique for the analysis of steels and metals. Utilizing linear heating and cooling experiments, DSC enables the identification of phase transitions, determination of their enthalpy, and facilitates the assessment of solidus-liquidus, indicating the temperatures at which the sample undergoes melting and crystallization.

App. Nr. 02-002-001 HDSC PT 1600 – Low alloyed steel – DSC

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.
