Influence of pre-alloying process on microstructure and components of 22MnB5 hot stamping steel coating

Journal of Hebei University of Science and Technology, 2017
Using coating on the hot forming steel can effectively avoid the surface defects such as surface oxidation and decarburization in the thermoforming process, and make the workpiece have a certain degree of corrosion resistance after molding.

Flow behaviors of 22MnB5 steel at a high temperature

Materials Research Express, 2019
Flow behaviors of 22MnB5 ultra-high strength steel (UHSS) at different temperatures and strain rates were investigated using uniaxial tension tests. The variables of the Arrhenius model, which involved n, Q, α, and lnA, was calculated using a fifth order polynomial fitting method.
