The evolution of the microstructure and texture in copper has been studied during repetitive extrusionupsetting(REU) to a total von Mises strain of 4.7 and during subsequent annealing at different temperatures. It i...
Thermomechanical processing as a combination of cold rolling and annealing was performed on austenitic stainless steels 301,304 and 304L. Two cold rolling steps each one up to a reduction of 75% were combined with an ...
