Real-time insight into the grain growth with the non-destructive NDT technology laser ultrasound
In cooperation with Linseis Messgeräte GmbH and RECENDT GmbH (Research Center for Non-Destructive Testing GmbH), a real-time grain size determination system based on a dilatometer system (DIL L78/RITA) and an adapted laser-ultrasonic system (LUS) was developed.
Phase transition of a substance: Melting
Melting describes the phase transition of a substance from a solid state to a liquid state.
What happens during Crystallization (Tc)?
Crystallization describes the transition of a substance into a crystalline state. This can occur from the gas phase, solid phase or liquid phase.
Investigations of Hydrogen Storage Solutions
As the mass-specific energy density of hydrogen (33.3 kWh/kg) is one of the highest of all fuels, the use of hydrogen for mobility and as an energy storage medium was and is of great interest.
Specific heat capacity
The specific heat capacity indicates the ability of a substance to store heat. This material quantity corresponds to the amount of heat required to heat a certain amount of a substance by one Kelvin.
PCM – Phase Change Material
A second heat reservoir is the simple increase in temperature without a phase change. For such applications, the specific heat capacity of the storage material and its density should be high.
Thermal contact resistance
The thermal contact resistance characterizes the transfer of heat at the interface between two solids.
3D printing in ceramics
Ceramics are used in many areas of industry. As a rule, ceramics are first formed as green bodies from raw mass before this “green body” is then treated in a special way and fired (so-called sintering).
3D Printing Polymers
Injection molding, often also referred to as injection molding or injection molding process, which is based on primary molding. The injection molding machine liquefies the plastic in granulate form.
Thermal insulation and thermal insulation materials
Whenever objects with different temperatures are in physical contact or are in the area of radiant influences, heat exchange takes place.
