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

通过热机械闪蒸处理提高哈德菲尔德钢的耐氢脆性

为了实现对氢脆的高抵抗力，通过新型的闪速热机械处理将纳米孪晶的微观结构引入了高碳锰钢中。纳米孪晶晶粒降低了氢在散装材料中的扩散性，尽管它吸收的氢比无孪晶的试样还多。此外，已经表明，在电化学氢填充后，纳米孪晶的微观结构可以减少塑性变形过程中的位错滑移，从而形成精细的双板。
