摘 要：With the X65 pipeline steel as raw material,we researched the influence of Ce on the organization and the low-temperature impact toughness.The result of the experiment was that:Ce had big influence on the organization and mechanics capability of X65 pipeline steel,Ce could thin the solidification to improve the capability of the steel.1# sample that was X65 pipeline steel without RE had dimple and uneven,its dimple and grain size was biggish;1# sample with RE’s dimple was small and uniform.The low-temperature impact and impact energy of 2# sample with RE were both higher.
