Abstract Bimetallic copper-steel composite could be an effective structural material to improve the performance of traditional nickel-aluminum bronze (NAB) ship propeller due its high strength and corrosion resistance. In this work, defect-free NAB coatings has been successfully fabricated by laser direct depositing technique on 17-4PH stainless steel substrate. The phase constitution, microstr...

Residual stress is a crucial element in determining the integrity of parts and lifetime additively manufactured structures. In stainless steel Ti-6Al-4V fabricated joints, residual causes cracking delamination brittle intermetallic joint interface. Knowledge degree at interface is, therefore, important; however, available information limited owing to joint’s nature its high failure susceptibili...

(AlCrTiMoV)N high entropy nitride film was prepared on 17-4PH stainless steel substrate using cathodic arc evaporation (CAE). The composition, microstructure, and thermal stability were investigated scanning electron microscopy (SEM), transmission (TEM), X-ray diffraction (XRD). Mechanical properties such as hardness Young’s modulus coating performance against wear erosion also evaluated. resul...

The performance of wrought and post-build heat treated, additively manufactured SS17-4PH stainless steel was evaluated to determine whether additive processing can produce material with a similar corrosion resistance the alloy in form, establish manufacturing (AM) conditions alter electrochemical required for attack. Samples built by laser powder bed fusion (LPBF) from nitrogen-atomized argon-a...

The aim of this work was to compare the microstructures 17-4PH martensitic stainless steels (MSSs) obtained by conventional manufacturing (CM), and additive (AM) using laser beam melting (LBM) process. Both materials were studied after same H900 heat treatment. Significant differences in microstructure observed between two MSSs, with a higher austenite content for AM-H900 sample, as compared CM...

Abstract 17-4 PH stainless steel alloy has been widely used in the field of defence industry such as weapon equipment, aerospace, nuclear energy, and so on because its high strength, toughness, temperature resistance, corrosion resistance. In order to meet flexible manufacturing requirements multi-variety small batch complex structure products with lower cost higher efficiency, selective laser-...
