Nature Materials publishes XJTU breakthrough
Researchers at the State Key Laboratory for Mechanical Behavior of Materials at Xi'an Jiaotong University (XJTU) have designed a fully quantitative in situ transmission electron microscopy nanomechanical test method to quantify the interaction between hydrogen and dislocation at the level of a single dislocation for the first time, using single-crystal pure iron as a model material.
The results were published in Nature Materials under the title Quantitative tests revealing hydrogen enhanced dislocation motion in α-iron.
