Study on static recrystallization behavior of L360 pipeline steelduring hot rolling process
The recrystallization behavior of austenite is one of the main factors which affect the microstructure and mechanical properties of the hot rolled steel strip.Based on the thermal simulation test, the static recrystallization behavior of L360 pipeline steel with Nb and Ti during hot rolling process was studied by means of stress relaxation method and microstructure observation method.The effects of strain, deformation temperature, strain rate and grain size of initial austenite on the static recrystallization of austenite were analyzed.By the linear regression analysis, the static recrystallization activation energy of the test steel was calculated, that was 203 kJ, and the static recrystallization kinetics equation was also obtained by regression analysis.
