摘要：
The relation between microstructure characteristics and mechanical properties of X80 pipeline steels was investigated using optical microscopy,scanning electron microscopy,etc.It is shown that the structure consists of polygonal ferrite(PF),quasi-polygonal ferrite(QPF),acicular ferrite(AF),and granular bainitic ferrite(GF).With increasing volume fraction of M-A islands(below 3%),the yield strength increases.With increasing content of higher angle grain boundaries(HAGBs),the yield strength,elongation,and DWTT properties at-15 ℃ increase,and the volume fraction of M-A islands reaches its highest point in the steel containing the most volume fraction of GF.
