Effect of Aspect Ratio on the bending property of Titanium Fiber Formed by the Compression Shearing Method at Room Temperature

Abstract

Titanium fiber thin plates were formed by a compression shearing method at room temperature. The effect of the fiber aspect ratio on the microstructure, strength properties, and porosity of the formed samples were examined. As a result, the surface roughness was constant at approximately 5.4um, and the patterned indented surface was homogeneous and isotropic. The porosity of the samples was found to increase from about 32.1 to 39.9% by increasing the aspect ratio of the titanium fiber. The elastic modulus of the samples increased with increasing the aspect ratio of the titanium fiber. In addition, the bending elastic modulus and the bending strength remained constant at approximately 50 GPa and 310 MPa, respectively.
