A selection of nine heats of line pipe steel from the same project with different Ti and N content were used to evaluate the effects of Ti/N ratio on weld zone microstructure, hardness and prior austenite grain size (PAGS) in the coarse grained heat-affected zone (CGHAZ). It was shown that the microstructure of the base metal (BM) mainly consisted of fine grained polygonal ferrite with fine islands of pearlite. The weld metal (WM) microstructure was predominantly acicular ferrite with a small volume fraction of pro-eutectoid ferrite. The CGHAZ consisted of bainitic ferrite and islands of martensite-austenite. The inside region of …

The continuous cooling transformation characteristics of novel bainitic steels have been studied, both under ordinary conditionsand whilst subjected to a 30 T magnetic field. The magnetic field has been found to completely change the microstructure obtained,from a mixture of bainite and martensite to one containing an incredibly fine pearlite with an interlamellar spacing of about 50 nm.As a consequence, the pearlite is found to be much harder than any other examples found in the published literature.
