説明
The ultrasonic wave velocities in a polycrystalline aggregate are sensitively influenced by texture changes due to plastic deformation, and their relationship was systematically analyzed by Sayers. According to Sayers's proposed model, it is possible to construct ultrasonic pole figures via the crystallite orientation distribution function (CODF), which can be derived by using ultrasonic wave velocity changes. In the previous paper, the Sayers's model was examined by experimental work and the effect of plastic deformation on texture development of an aluminum alloy specimen was studied by using ultrasonic pole figures as one of its applications. In the present paper, the ultrasonic pole figures based upon Sayers's model are constructed under various loading conditions of uniaxial tension, pure torsion, biaxial tension-compression, biaxial compression and biaxial tension, respectively. To examine its accuracy and reliability, the ultrasonic pole figures are compared with ones analyzed by the finite element polycrystal (FEPM), which has already been considered as a well-developed technology for the analysis of microstructural behaviors due to plastic deformation. The results show a remarkable qualitative similarity among the two methods.
