AN372 – Heat capacity of a steel betwwen 50°C and 1550°C (liquid state)-zh



AMulti HTC is used with heat flux DSC transcuder. Sample : steel Sample size : Æ 5,0 mm, h=15 mm. The analysis is done in a platinum crucible + alumina sleeve. The determination of Cp requires three successive heating :
– without sample – with a piece of alumina as a standard
– with a piece of steel
The three heating have been done from ambient up to 1550°C at 10 K.min-1. The used atmosphere is helium.


The heat capacity of the steel is calculated from the experimental curves. The Cp could be calculated also in the liquid state at 1550°C.
