Course detail

Technological Properties of Materials

FSI-WTVAcad. year: 2014/2015

Technological properties of materials explained, in particular, on the basis of materials problematic. The technological properties included concern metallic materials (castability, formability, weldability, and machinability). Technological properties of non-metallic materials are incorporated in courses dealing with them.
