| Abstract: | The role of micro- alloy Nb in low- carbon micro -alloyed steel is analyzed, the process is discussed to delay the recrystallization and make grain finer by adding micro Nb. It is showed from experiment that there is still precipitation appeared under low temperature even micro Nb has extracted when temperature is high. |
