Influence of Cooling Rate on Formation of Structural and Textural States in Ferritic-Martensitic Stainless Steel with 12 wt.% Chromium
The structural and textural states formed in samples of stainless steel of the ferritic-martensitic class, close in composition to Cr12NiMoWoSiVNb, are studied by the method of scanning electron microscopy using orientation analysis and software for reconstruction of high-temperature austenitic grains. The samples are taken from a hot-rolled pipe that has been quenched in water and tempered at a high temperature. The samples are heat treated by holding at 950°C and cooling at different rates (in water, in air, in the furnace). At all the cooling rates, the steel structure consists of grains of δ-ferrite and martensite and contains coarse precipitates of (NbMo)(CN) carbonitrides and finer M23C6 and (VNb)C carbides. When the phase transformations occur in the sequence δ + α′ → δ + γ → δ + α′, the steel inherits structural and textural features due to nucleation of a new phase on special boundaries.
