High Temperature Deformation of an ECAP Al.Mn Based Alloy

Popis výsledku v původním jazyce

The equal-channel angular pressing (ECAP) is one of the most efficient methods of grain refinement. The fine grain size can enhance the plasticity of materials at high temperatures and many ECAP alloys exhibit even superplastic behaviour in the case thatthe fine-grained structure remains stable at high temperatures. An Al-Mn-based alloy modified by the addition of Sc and Zr was produced using ECAP. The microstructure investigation using TEM and EBSD methods revealed a mixture of well defined grains with the submicrometer size, and severely deformed regions in the as-prepared state. Annealing at elevated temperatures resulted in a recovery of the severely deformed microstructure. The submicrocrystalline microstructure is retained after annealing up to400 °C, a slight grain growth is observed at higher temperatures. A relatively large fraction of low-angle boundaries is typical for the investigated material even after annealing at the highest temperatures. Special tensile tests perform
