Labs and Equipment
Powder metallurgy lab
In the powder metallurgy lab powder processing, powder characterisation and shaping of parts is perfomed. After that heat treatments can be performed in the heat treatment lab. Thus accept for the powder production every part of the process chain of powder metallurgy is represented at the chair.

Heat treatment/sintering lab
In the heat treatment lab samples produced in-house or from outside can be heat treated. This can happen with different atmospheres at temperatures up to 1500 °C. Possible heat treatments are the debinding and sintering of green bodies, homogenizing, stress relieving, coarse grain tempering, recristallisation and more.
