    摘要
  • 摘要: 通過實驗室熱模擬和軋制實驗研究了添加0.21%Al對成分為0.05%C-1.7%Mn-0.4%Si-0.05%Nb-0.03%Ti(質量分數)的微合金鋼奧氏體分解動力學的影響.結果表明:加入0.21%Al在冷速為10℃/s范圍內明顯抑制奧氏體向先共析鐵素體的轉變,提高了貝氏體的淬透性;對于780℃終軋后在600℃等溫20min的鋼板,Al通過提高碳的活度減輕或避免了帶狀組織的形成,明顯提高了軋制鋼板的力學性能.

     

    Abstract: The influence of 0.21% Al (mass fraction) on the kinetics of austenite decomposition in microalloyed steel containing 0.05%C-1.7%Mn-0.4%Si-0.05%Nb-0.03%Ti was studied. The results show that the hardenability of the experimental steel increases apparently by adding 0.21% Al when the cooling rate is in the range of 1~30 ℃/s. For isothermal treated plates at 600 ℃ for 20 min after rolling process, the banding microstructure of the plates containing 0.21% Al is abated or avoided and the overall mechanical properties of the plates is promoted greatly.
