Abstract

High-strength materials are required for aerospace and transport applications. Severe plastic deformation results in grain refinement, which produces high-strength materials. In this study, thin titanium plates were formed by compression shearing at room temperature. Grain refinement in thin Ti plates occurred upon varying shear strain. Transmission electron microscopy observations revealed that the microstructure involved grain refinement. It was found that diffusion bonding occurs upon uniaxial compaction. Compression stress and shear strain concentrated stress at bonded interfaces and subgrains formed in these stress-concentration regions. In addition, subgrain area increased with increasing shearing strain. Plastic deformation resulted in a dense, homogeneous material.
