| Abstract |
The production of ultrafine grained (UFG) Al alloys with improved tensile and fracture strength as compared to its bulk alloys has attracted lot of attention in aerospace and automotive industries due to the possibility of realizing very high specific strength with significant weight reduction of structural components fabricated by using these UFG materials. Ultrafine grained AA 2014 alloy has been produced by Cryorolling and Multiaxial forging and its tensile behaviour was investigated in the present work. FEM simulation of deformation characteristics of UFG Al alloys was performed using the experimental tensile results for various cryogenic temperatures in order to understand its strain hardening behaviour with respect to the bulk alloy. It is observed that the tensile strength of UFG Al alloy has improved significantly as compared to its bulk Al alloy, due to the increased dislocation density and grain size effect. ABAQUS software was used for the FEA of tensile property of UFG Al alloys at different processed temperatures and it has been shown that the simulated strain hardening behaviour of the Al alloy matches with that of experimental results. |
