Texture and strain rate sensitivity analysis of solid solution and precipitation hardening aluminum alloys processed by repetitive corrugation and straightening

Abstract. The potential of improving the mechanical strength by RCS process is evaluated on 5754, 6061, and 7075 aluminum alloys, which present different hardening mechanisms related to their respective alloying elements. This work compares evolution texture properties alloys through processing. were micro-hardness measurements, tensile tests at temperatures, strain rates evaluate strain-rate sensitivity. results showed that after two passes, 6061 5754 a relatively high sensitivity 300°C. In addition, an increment 27%, 22%, 15% in hardness was obtained for respectively. Showing improvement resistance due mechanism. Furthermore, crystallographic characterized obtention pole figures X-ray diffraction calculation orientation distribution functions. same trend three i.e., initial components conserved, but texturized volume decreased.
