Laser powder bed fusion (L-PBF)-processed 17-4 PH stainless steel (SS) generally exhibits a non-equilibrium microstructure consisting mostly of columnar δ-ferrite grains and substantial fraction retained austenite martensite, contrary to SS wrought with fully martensite structure coarse grains. Despite the different microstructures L-PBF SS, post-processing is typically performed using conventi...

Abstract The most relevant criticalities of parts produced by material extrusion additive manufacturing technologies are lower mechanical properties than standard performances, the presence pores caused method, and issues related to interface between layers rods. In this context, heat treatments can be considered an effective solution for tailoring behavior different application fields, especia...

The aim of this study was to assess the surface characteristics and to compare the corrosion potential of metal brackets and wires in environments containing different media. Four brands of metal brackets and two types of orthodontic wires [stainless steel and nickel-titanium (NiTi)] were investigated. An electrochemical assay was used to compare the corrosion potential (V) of the brackets and ...
