RESUMO

The main goal of this work is to study workability of u1trafine gold wires in wiredrawing. Putting together the fundamentals of Irechanical plasticity, material properties and ductile fracture criteria , it may be established the workability criteria. The first part of this work involved the development of drawing machines. The second part was the study of the ductile fracture mechanisms of the wires and the establishement of workability criteria , which were applied to the process conditions of this work. Some suggestions were done in order to avoid wire breaks
