概要
- 論文の詳細を見る
Ultrafine grained microstructures and micro-textures formed dynamically during single-pass, high-Z, large-strain deformation have been analyzed in 0.15C steel. A single pass compression technique capable of imposing large plastic strain up to 4 was employed in the present study. Hardness test data revealed work hardening type behavior by pancake type grains while softening behavior was exhibited by equiaxed grains. Detailed micro-texture analysis carried out on the specimens deformed at different temperatures and strains rates in the warm working region revealed no significant difference among them. Even up to fairly high deformation temperatures of 923 K the texture consists of typical deformation components. Finally, based on the results obtained, fundamentals of ultrafine grained product design are discussed.
