And the way they made these predictions was they put them very close to the core and over a period of time they would take out specimens and determine what the degree of embrittlement was.
With increasing corrosion time the impact toughness of high Mn steel obviously decreased. The major mechanism was effect of the caustic embrittlement cracking.
随着热强碱腐蚀时间的延长，高锰钢的冲击韧度明显降低，碱脆开裂是造成高锰钢冲击韧度下降的主要原因。

The high Mn steel caustic embrittlement cracking was distinct in corrosion. With increasing corrosion time the impact toughness of high Mn steel obviously decreased.
