摘要

摘要: 利用Gleeble1500熱模擬機研究了Nb質量分數0.089%的高溫熱機械軋制鋼(4^# Nb鋼)在粗大奧氏體晶粒條件下的靜態再結晶規律.作為對比,同時研究了一種鈮質量分數0.049%的低碳含鈮鋼(2^# Nb鋼)的靜態再結晶規律.實驗結果表明:4^# Nb鋼的靜態再結晶動力學過程比2^# Nb鋼慢,在高溫時差異較小;隨著形變溫度的降低,4^# Nb鋼的靜態再結晶動力學被極大地延遲.根據實驗數據建立了靜態再結晶模型,該模型對軋制工藝的制定有一定的指導意義.

Abstract: The static recrystallization behavior of a high temperature processing (HTP) steel containing 0.08% Nb (4^#Nb steel) with coarse austenite was investigated by using a thermo-mechanical simulator Gleeble 1500. A low carbon steel containing 0. 049% Nb (2^# Nb steel) was also studied as a comparison. The results indicate that the static recrystallization kinetics process of 4^# Nb steel is slightly slower than that of 2^# Nb steel at high deformation temperature. The recrystallization of 4^# Nb steel is greatly retarded with decreasing deformation temperature. According to experimental data, a mathematical model of static recrystaUization was developed, which can provide theoretical guidance for designing the industrial rolling procedure.
