https://doi.org/10.1007/978-3-642-68670-2 properties mainly due to a smaller and more homogeneous prior austenite grain size. Niobium additions enable higher process efficiency by high temperature carburizing. In forging steels microalloying controls the phase transformation during cooling after forging and enables shorter process routes.botany 发表于 2025-3-30 20:32:49

The results show that at the cooling rates of 1°C/s or below, ferrite initially formed and continuously rejecting C into the untransformed austenite, which transforms to C-rich lower bainite at lJAMB 发表于 2025-3-31 13:52:02
