摘要：

The microstructural characteristic and its effect oil toughening of an ultralow carbon acicular ferrite pipeline steel were investigated by means of mechanical testing and microstructural analysis. Experimental results showed that the acicular ferrite dominated microstructure can be obtained for the ultralow carbon pipeline steel through the clean melting and the optimized thermo-mechanical processing. It was also found that there exists a layer of thin martensite film at the grain boundary of ferrite. All these microstructural characteristics play important roles in enhancement of toughening for the ultralow carbon acicular ferrite pipeline steel.
