Relationship between a bainitic structure and the hardness in the weld zone of the friction-stir welded X80 API-grade pipe-line steel = Odvisnost med bainitno mikrostrukturo in trdoto v področju zvara pri torno vrtilnem varjenju jekla X80 API za cevovodeAydin, HakanThe present study focuses on the morphology of the weld zone, especially on the quantitative microstructural characterization of bainitic structures, and the relationship between post-weld bainitic ... structures and the hardness at the weld zone of the friction-stir welded X80 API-grade pipe-line steel. The employed rotating and traverse speeds of the polycrystalline cubic boron nitride tool during the friction-stir welding process were 350 r/min and 12.7 cm/min (5 inch per minute), respectively. A microstructural analysis of the weld was carried out using optical microscopy, orientation imaging microscopy and transmission electron microscopy, and the hardness variation was also mapped across the weld-plate cross section. The frictional heat and plastic flow during friction-stir welding create a granular bainitic structure (the stir zone), a lath-like upper bainitic structure (the hard zone) and a recrystallized equiaxed polygonal ferritic structure (the heat-affected zone) in the weld zone. The maximum hardness was observed in the classical upper bainitic microstructure in the hard zone. The minimum hardness was found in the heat-affected zone. A good correlation between the post-weld bainitic structures and the hardness in the weld zone was obtained; the hardness increases almost linearly with the decreasing bainite-lath and packet sizes.Source: Materiali in tehnologije = Materials and technology. - ISSN 1580-2949 (Letn. 48, št. 1, jan.-feb. 2014, str. 15-22)Type of material - article, component part ; adult, seriousPublish date - 2014Language - englishCOBISS.SI-ID - 1030314
