本文首先阐述了研究轨钢应力腐蚀的意义。在国内首次开展了对轨钢应力腐蚀门槛应力强度因子K_(ISCC)的测定研究,并取得了AP1轨钢在蒸馏水和3.5％盐水下的K_(ISCC)值。从而为轨道的设计和维修提供了依据。
This paper first expounds the significance of studying rail stress corrosion. For the first time in China, the stress intensity factor K_ (ISCC) of rail corrosion stress threshold was studied and the K_ (ISCC) value of AP1 rail steel in distilled water and 3.5% salt water was obtained. Thus providing the basis for the design and maintenance of the track.
