Strain path effects on texture development in aluminium
During most metal forming processes the material undergoes a complex strain history. This paper considers simple laboratory testing to simulate a variety of strain path changes. Samples of an aluminium-1%manganese alloy have been deformed using combinations of channel die and free compression to obtain a range of strain path change angles of 0degrees, 90degrees (2 ways), 120degrees and 180degrees. Following deformation samples were annealed to determine the effect of the strain path change on the recrystallisation. The textures of both the deformed and recrystallised material have been measured using x-ray texture analysis. The work has show that there is a large effect of the strain path on the work hardening behaviour of the material and on the deformation texture and recrystallised kinetics.
