production of defects by cross-slip, (iv) junction formation (e.g. Lomer-Cottrell locks), and (v) annihilation of oppositely-signed dislocations or abso... IJ Beyerlein,CN Tomé - 《International Journal of Plasticity》 被引量: 293发表: 2008年 Work Hardening and Dislocation Arrangement of fcc...
During strain hardening stage, abundant Lomer-Cottrell (L-C) locks formed both within nanograins and against twin boundaries. Two major mechanisms were identified during interactions between L-C locks and twin boundaries. Quantitative nanoindentation experiments recorded show an increase of yield strength...
