【摘要】 在硫化氢水溶液环境中用WOL试样测定了16Mn钢的应力腐蚀门限强度K_ISCC及裂纹扩展速率da/dt。为了监测裂纹扩展,应用了测力螺栓方法。实验表明,此测力螺栓方法既可保证一定的精度要求,也便于操作。更多还原

【Abstract】 Stress Corrosion threshold stress intensity KISCC and stress corrosioncrack growth rate da/dt have been measured for 16Mn steel in H2S aqueous environments with WOL specimens. In order to monitor crack growth in WOL specimens, a technique of instrumented bolt was used in this work. It is found that the technique of instrumented bolt provides several advantages, including enough accuracy and convenient operating.更多还原
