| Abstract: | B2F steel rolled by newly developed technology is investigated with the positron annihilation technique. The relationship between the average lifetime of positron and the rolling pressure, the ratio of rolling speeds and the mechanical properties are measured. It is shown by electron microscope observation that, judging by the positron lifetime, there are a lot of dislocations and vacancy cluster defects in B2F steel during rolling. |
