|On-Site Speaker (Planned)
The high cycle fatigue behavior of Armco iron severely deformed by ECAP at room temperature through route Bc until 8 passes, was studied and compared with the same material in the annealed state. The fatigue limit after ECAP processing increased by more than 250% rising from 274MPa to 717MPa. The microstructure was characterized by EBSD before and after the fatigue tests and it was observed in both sample an increment in the fraction of Low Angle Grain Boundaries at high number of cycles to failure. A texture analysis for the materials after the fatigue failure was also done. This study shown a preferential orientation towards the γ fiber for both materials.
