In-situ Neutron Diffraction Study on Work-hardening Behavior in a Ferrite-Martensite Dual Phase Steel

International Journal of Automotive Engineering, 2011
Strength and work-hardening in steels are discussed from the viewpoint of heterogeneous deformation. In-situ neutron diffraction studies made it clear that misfit strains between grains accompanied grain-scaled internal stresses (intergranular stress ...

Spinodal decomposition and radiation damage of a FeCuMnNi high-entropy alloy

Nuclear Materials and Energy, 2023
The precipitation of Cu-rich phases during the irradiation process will reduce radiation resistance in Fe-Cu-Mn-Ni reactor pressure vessel steels. Therefore, high-entropy alloys with excellent radiation resistance are expected to replace reactor pressure

Hole expansion of dual phase steels [PDF]

WIT Transactions on The Built Environment, 2012
In this work, the stretch-flangeability of dual phase (DP) steels was investigated through the hole expansion (HE) tests for three DP980 steel sheet samples. In order to understand the effect of hole surface quality on the HE results, the specimens were prepared with three hole machining methods, namely, electrical discharge machining (EDM), punching ...
