EBSD Study on Boundaries and Texture of 1235 Aluminum Alloy Affected by Strain Rates
Texutre evolution of 1235 aluminum alloy deformed at different strain rates was studied by dynamic thermal-simulated technology with the aid of some modern analytical and testing technique called election backscatter diffraction (EBSD). The results showed that the effect of strain rate on grain boundary and deformation texture of 1235 aluminum alloy was obvious. At deformation temperature for 400°C and distortion for 50%, the value of the maximum density level came to the minimum by 11.489 at the strain rate for 0.01s-1. The texture was weaker for the grains were less likely to rotate. The relative volume of textures increased as the strain rate increasing. The relative volume of textures was merely 1.95% at strain rate for 0.01s-1 but ascended to 5.4% at strain rate for 50s-1.
