The results showed that the corrosion weight loss rate of high Mn steel was distinctly greater than that of medium carbon chromium steel. The high Mn steel caustic embrittlement cracking was distinct in corrosion.

结果表明，高锰钢的平均腐蚀速率显著高于中碳铬合金钢，腐蚀过程中高锰钢有较严重的碱脆开裂现象。

With an increase of the chromium content in the cast steel, active dissolving corrosion increased, however, tendency of caustic embrittlement cracking decreased.

随着钢中含铬量的增加，试验材料的活性溶解腐蚀失重增大，但碱脆开裂的倾向减少。

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 experimental results show that steel fiber reinforced self-stressing concrete can significantly increase the cracking load of penstock.

试验结果表明，钢纤维自应力混凝土能够明显地提高压力管道的抗裂承载力。
