摘要
Abstract
The tensile tests at the high temperature of 600～1 000 ℃ were carried out on pipeline steel 316 LN, and the tensile microstructures were investigated by optical microscope and TEM.The results show that the grains are elongated at600 ℃, the dislocations aggregate at grain boundaries, and no dynamic recrystallization.However, the deformed grains gradually disappear when the temperature rises to 800～1 000 ℃, and dynamic recrystallization occurs, grain size increases, and dislocations gradually disappear.关键词
