Mechanical properties of submicrocrystalline commericial-aluminium alloys processed by severe plastic deformation via angular extrusion

Data on ambient temperature mechanical properties of submicrocrystalline commercial aluminium alloys are reviewed.The combination of strength, ductility and crack resistance characteristics achievable is comparable to, or even better than, that found in many high-strength conventionally treated precipitation-hardened alloys. For most of heat treatable alloys, the use of treatment involving severe plastic deformation for improving mechanical properties due to submicon structure processing is less effective. The nature of the effects of severe straining on aluminium alloys structure and properties is discussed.
