THERMOPHYSICAL TESTING LABORATORY
Room JK211
About:
Thermophysical Testing Laboratory (TTL) is part of the Department of Metallic Materials Science, Physical Metallurgy at the University POLITEHNICA of Bucharest is directed by Associate Professor Mihai Branzei.
This laboratory was established as a result of an agreement between ANTER Laboratories Inc. (a corporation of the Commonwealth of Pennsylvania, USA) and University POLITEHNICA of Bucharest, foundation called "European Thermophysical Testing Center - ETTC, since 2001. This agreement ended in 2007, at which laboratory belong aforementioned Department, also being integrated into the Biomaterials Centre -BIOMAT.
