HDSC PT 1600 – Low alloyed steel – DSC
Steel sample – Phase transition / melting / solidus-liquidus
Differential Scanning Calorimetry (DSC) is a common used technique for analysis of steels and metals. Linear heating and cooling experiments by DSC can identify phase transitions, their enthalpy and allow a solidus-liquidus determination which indicates at what temperature the sample is melting and crystallizing.
App. Nr. 02-002-001 HDSC PT 1600 – Low alloyed steel – DSC
The measurement shows the heating and cooling curve of a low-alloyed steel sample, measured by High Temperature Differential Scanning Calorimeter (HDSC PT 1600). At 734°C the change in the crystal structure and the change in the magnetic properties (ferromagnetic to paramagnetic) occurred. The melting point can be seen at 1411°C. The liquidus temperature was measured at 1473°C. All peaks are reversible and can be observed in the cooling segment as well (blue curve). The crystallization range goes from 1454°C to 1436°C and the phase transition to ferromagnetic takes place at 637°C.
