Microstructural Evolution of Al 1100 Aluminum Subjected to Severe Plastic Deformation

Microstructural Evolution of Al 1100 Aluminum Subjected to Severe Plastic Deformation

The goal of this 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...
