摘要: Abstract Nano-twins microstructures were introduced in a high carbon manganese steel by novel flash thermo-mechanical treatment order to achieve resistance hydrogen embrittlement. Nano-twinned grains decreased diffusivity through the bulk material, although it absorbed more than twins-free specimens. Moreover, was shown that after electrochemical charging, nano-twins can reduce dislocations glide during plastic deformation, resulting forming of fine twin plates.
