This week’s topic: Specific Heat Capacity of PBF Powder
We use Differential Scanning Calorimetry (DSC) heat flux method to measure the difference in heat to detect ExothermicA sample transition or a reaction is exothermic if heat is generated.exothermal and endothermal effects.
- The importance of heat capacity for any kind of thermal simulation
- The difference of the method of measuring the heat capacity compared to a conventional DSC measurement
- An application example with PA12
- Using the Specific Heat Capacity (cp)Heat capacity is a material-specific physical quantity, determined by the amount of heat supplied to specimen, divided by the resulting temperature increase. The specific heat capacity is related to a unit mass of the specimen.specific heat capacity to calculate the Thermal ConductivityThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity

Measuring Specific Heat Capacity to Simulate SLS Processes
Significant efforts have been made to model and simulate the Selective Laser SinteringSintering is a production process for forming a mechanically strong body out of a ceramic or metallic powder. Sintering process as information about the temperature field in lower layers is difficult to measure. Learn how the Specific Heat Capacity (cp)Heat capacity is a material-specific physical quantity, determined by the amount of heat supplied to specimen, divided by the resulting temperature increase. The specific heat capacity is related to a unit mass of the specimen.specific heat capacity can help!
In our next episode, we will talk about estimating residual stresses in PBF parts using DMA.
