Evolution of Rotated Cube Texture and Its Influence on the Mechanical and Fracture Properties of Al/Ti/Alumina Composites Fabricated via ARB
摘要
The evaluation focused on the major textural transition known as the Rotated Cube component within the Al/Ti/alumina composite generated through the accumulative roll bonding process. The effect of this transition on the mechanical and microstructural trade-off was investigated. Additionally, the influence of incorporating alumina particles through the anodizing process was taken into account. The texture evolution in the material was studied using the X-ray diffraction method. It was found that the Rotated Cube component was the typical texture component in Al/Ti/alumina composites. However, the formation of this component was suppressed in the composite containing the highest alumina content during the fourth cycle of the accumulative roll bonding process. A transition in texture from shear texture to β/τ fiber texture was also observed. Moreover, the effect of the Rotated Cube component on the mechanical properties and fracture behavior of the composites was investigated. It was found that the development of this texture component can strengthen the material’s response to the applied load. Moreover, fractography validated the displacement of dimples toward the direction of pronounced shear, attributed to the presence of the Rotated Cube component. The shift from shear to brittle fracture mode was observed to parallel the texture transition within the processed material.
