【 摘 要 】

The content of different Al elements in the wide thick plate of common carbon steel produces with the different AlN precipitation effect. The precipitation of different sizes and densities has an effect on the properties of steel plate. This study uses small furnace to smelt steel and rolling, through transmission electron microscope to observe the precipitation rule of AlN and the properties of steel plate, with the Al content from 0.030% to 0.070%, the lower Al content of the steel plate is higher than the Al content steel's mechanical properties.
