The University of Amsterdam organizes the course Metallography. This four-day course is given by prof. Paolo Piccardo (Associate Professor at the University of GENOA in Italy, Head of the Laboratory of Metals and Materials http://www.chimica.unige.it/inmet<http://www.unibo.it/faculty/carla.martini>.
Overview Metals record the very beginning of their life (smelting) to the actual end product (in our hands) in their microstructure. A trace of their origin can remain inside the metal matrix and this can affect the corrosion products. The manufacturing processes (e.g. deformation, annealing) modifies the microstructural features, having an effect on the mechanical and chemical properties. The alteration process the metal has undergone over time is related to the surrounding environment and to the metal substrate's nature, both marking the object in a visible way. All of these signs are coded inside the objects and it is our goal to offer metallography together with the careful observation of the object as tools suitable to decode the "language of the metals". By definition metallography represents the connection point between the chemical composition, the thermal history, the mechanical treatments (the three of them affecting the microstructural features) and the mechanical properties (depending on the microstructure). The correct use of sampling, observation by optical and scanning electron microscopy supported by spectroscopic investigations as EDX and WDX for the composition or Raman and XRD for the corroded patina and non-metallic additional layers should be the main tools for investigation. During lectures these tools will be introduced by case studies on the most common metals and alloys. In order to make the classes more effective a short introduction on metals, alloys, microstructures and mechanical properties will be offered. The case studies will be supported by afternoon practical sessions referring to the matters discussed during the morning session. The gathered information will be a valid support for all restoration activities, and most importantly, it's a valuable tool for conservators not only to preserve the object but also to keep alive its history and the "hand of the individual" who was behind its manufacturing and use.
