The effects of additive manufacturing (AM) and post-AM heat treatment on microstructural characteristics pitting corrosion 2205 duplex stainless steel were studied benchmarked against its conventionally hot-rolled counterpart. rapid solidification possible loss N associated with AM resulted in a non-equilibrium microstructure dominated by ?-ferrite minor fraction austenite abundant Cr2N precipi...

A laminated structured 2205 duplex stainless steel (DSS) with graded grain size was prepared via aluminothermic reaction and subsequent hot rolling deformation of 80% at 1000°C, its mechanical properties, strengthening toughening mechanism were studied. Our materials have extraordinary elongation 54% high tensile strength 990 MPa. The lamellar structure is characterized heterogeneous lamella au...

The detrimental precipitation at the 2205 duplex stainless steel (DSS) grain boundaries has characterized material to have poor workability after being hot-rolled. However, in microstructure is largely influenced by cooling rate or method. There an insufficient investigation of this steel's grade interfaces and rationale its workability. This study investigates influence heat treatment hot-roll...
