Paper Title:
Influence of Second-Phase Particles on Microstructure Evolution and Mechanical Behavior of Ultrafine Grained Al-Alloys Produced by Severe Plastic Deformation
  Abstract

In present investigation the influence of second phase particles on microstructure evolution during confined channel-die pressing (CCDP) and mechanical behaviour after CCDP were studied using two-phase Al alloys of Al-1.5Mn and Al-5Zn-1.6Mg. The investigation results revealed different grain refinement kinetics during CCDP and distinct mechanical behaviours after CCDP for both alloys. The results are discussed based on the influence of the second phase particles on dynamic recovery and the interaction with mobile dislocations during plastic deformation.
