Nanoscale-twinning-induced strengthening in austenitic stainless steel thin films Academic Article uri icon

abstract

  • Magnetron-sputter-deposited austenitic 330 stainless steel (330 SS) films were fabrictaed. High-resolution transmission electron microscopy revealed that sputtered 330 SS coatings are heavily twinned on {111} with nanometer scale twin spacing. Molecular dynamics simulations show that twin boundaries are very strong obstacles to slip. The results provide a new perspective to producing ultrahigh strength monolithic metals by utilizing growth twins with nanometer-scale spacing.
