摘要：
The 42CrMo/Q235 laminated shaft was formed by cross wedge rolling, and the microhardness of 42CrMo/Q235 laminated shaft composite interface was tested. The effects of forming angle α, broadening angle β, area reduction Ψ, rolling temperature t and substrate diameter d on the interfacial microhardness were studied. The results show that the rolling temperature and section shrinkage have a great influence on the interfacial microhardness, while the substrate diameter, broadening angle and forming angle have a little influence on the interfacial microhardness. With the increase of rolling temperature, the microhardness of the same position decreases. The microhardness of the same location increases with the increase of the area reduction. With the increase of substrate diameter, the microhardness of the same position increases slightly, but the extent of increase is not large. With the increase of forming angle and broadening angle, the microhardness at the same position increases slightly, but the increase is not significant. The results can be used as a reference for determining the process parameters of 42CrMo/Q235 cross wedge rolling and improving the interface bonding quality. © 2020, Central South University Press.
