【摘要】 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。更多还原

【Abstract】 The significance of stress corrosion test for rail steel is demonstrated. The threshold stress intensity factor under stress corrosion, KISCC for rail steel, for the first time, is investigated; and values of KISCC for AP1 rail steel in both distilled water and 3.5% salt solution, which offer basic data for track design and maitenance, are obtained.更多还原
