摘要: Abstract Small-scale mechanical testing techniques are currently being explored and developed for engineering applications. In particular, micro-tensile can add tremendous value, since the entire stress-strain curve, including strain to failure, be measured directly. this work, 304 stainless steel specimens irradiated with 2 MeV protons 10 dpa (full-cascade setting in Stopping Range of Ions Matter, SRIM, software) at 360 °C was evaluated using testing. It found that even on micron scale, corresponds well macroscopic expectations. addition, a new approach analyzing sudden slip events is presented.
