| Abstract: | With the inspection of impact work of V notch at different positions of 310 Z shaped steel at -40 ℃ and relevant metallographic structure, it is analyzed that the influences of metallographic structure on low - temperature impact work for 310 Z shaped steel. The result indicates that low - temperature impact work is different at different positions for identical 310 Z shaped steel. The main factors are differences of grain size ,form ,and distribution of ferrite. |
