摘要：
High-strength pipe steel structure is studied by light and scanning microscopy. Extensive areas, identified previously as “lath morphology bainite” are analyzed. It is shown by means of EBSD analysis that the areas studied are in fact large grains of bainitic nonequilibrium ferrite within which carbon is bonded in microalloying element carbonitrides and is restrained by dislocations.
