内容記述 | Uniaxial compression tests were conducted on Al-3mass%Mg alloy and Al-3mass%Mg-0.2 mass%Sc alloy under various amounts of strain and strain rate at 723K. High temperature yielding phenomena were observed at 723K and strain rates ranging from 1.0×10^-4s^-1 to 5.0×10^-3s^-1. Texture examination elucidated that fiber textures were constructed in all the deformation conditions. Texture measurement revealed that the main component of the fiber texture changed from {011} + {001} to {001} with an increase in strain when the viscous motion of dislocation is the dominant deformation mechanism in the binary alloy. Texture changes are also seen at strength of the {001} component in the binary alloy that increased with increase in strain rates between 5.0×10^-4s^-1 and 5.0×10^-3s^-1 up to a strain of -1.0, while in the ternary a1loy, neither variation of the pole density at {011} nor {001} in inverse pole figure is observed in the same deformation conditions. It is considered that A1_3Sc precipitates contribute to the suppression of grain boundary migration. This means that the grain boundary migration contribute to the development of {001} fiber texture. | |||||
