Effect of Grain Boundary Character Distribution on the Precipitation Behavior: A Comparative Study for 304 Steel and T91 Steel
When 304 steel and T91 steel are used as high-temperature structural materials, the presence of Cr-rich M23C6 carbides significantly impacts their properties. In the case of 304 steel, the inhibition of carbide precipitation is achieved by increasing the proportion of Σ3 grain boundaries (GBs). Conversely, for T91 steel, the proportion of random GBs increases following recrystallization. As a result, carbides precipitate within the ferrite grains instead of at the martensitic boundaries.
