The goal of this Hi-Ball Glasses document is to promote a sequence of bulk-deformation processes able to produce ultrafine grain and also nanostructured wires with adequate length to be interesting for processing in metallurgical industry.Samples of aluminum Al 1100alloy (98.41 % Al) were subjected to repetitive Equal Channel Angular Pressing at room temperature in 1 to 4 passes.Severe deformed specimens were cold classical plastic deformed in wires.Microstructural evolution and mechanical properties were investigated.

Optical microscopy progression is evaluated through a sequential interrupted process on each separate ECAP pass.The XRD studies Soccer - Socks reveal the influence of SPD on grain refinement of samples.A simply and new technology for obtaining intermediary products UFG and nanocristalline wires was developed.
