    • Abstract

  • The 316L/430 duplex stainless steels were prepared by selective laser melting in this study, using 316L and 430 mixed powders prepared by gas atomization as the raw materials. The microstructure, mechanical properties, and corrosion resistance of the 316L/430 duplex stainless steels before and after solution treatment were examined by optical microscope, electronic material testing machine, and electrochemical workstation. The results indicate that, as the solution temperature is 1250 ℃, the 316L/430 duplex stainless steels specimens show the better comprehensive mechanical properties, the tensile strength, yield strength, elongation, and microhardness are 830 MPa, 340 MPa, 25%, and HV 356, respectively, and the area ratio of ferrite to austenite is 45.7:54.3. When the solution temperature is 1150 ℃, the specimens have the better corrosion resistance, the self-corrosion current density and pitting potential are 3.196×10‒6 A/cm2 and −0.118 V, respectively.
