Microstructures and Properties of 17-4 PH Stainless Steel Fabricated by Selective Laser Melting
نویسندگان
چکیده
Precipitation-hardened (PH) stainless steels have been widely used as structural materials and related applications in marine environments, power plants (light-water and pressurized water reactors), and chemical industries because of their good mechanical properties and corrosion resistance at typical service temperatures below 300oC. 17-4 PH (A1S1630) stainless steel (15–17.5 Cr, 3–5 Ni, 3–5 Cu, <1 Mn, Si, 0.15–0.45 Nb, balance Fe in w%) is a martensitic stainless steel strengthened by precipitation of Cu-rich spherical particles in the martensite (ク) matrix (bcc, a = 2.86 Å) especially in the H900 condition [temper treatment at 900oF Journal of Materials Research and Technology

Data demonstrating the effects of build orientation and heat treatment on fatigue behavior of selective laser melted 17–4 PH stainless steel
Axial fully-reversed strain-controlled ([Formula: see text]) fatigue experiments were performed to obtain data demonstrating the effects of building orientation (i.e. vertical versus horizontal) and heat treatment on the fatigue behavior of 17-4 PH stainless steel (SS) fabricated via Selective Laser Melting (SLM) (Yadollahi et al., submitted for publication [1]). This data article provides deta...
متن کاملMechanical Properties of Austenitic Stainless Steel Made by Additive Manufacturing
Using uniaxial tensile and hardness testing, we evaluated the variability and anisotropy of the mechanical properties of an austenitic stainless steel, UNS S17400, manufactured by an additive process, selective laser melting. Like wrought materials, the mechanical properties depend on the orientation introduced by the processing. The recommended stress-relief heat treatment increases the tensil...

متن کاملMECHANICAL PROPERTIES OF SELECTIVE LASER MELTED AlSi10Mg: NANO, MICRO, AND MACRO PROPERTIES
The selective laser melting (SLM) of aluminium alloys is of great current interest at both the industrial and research levels. Aluminium poses a challenge to SLM compared with other candidate materials, such as titanium alloys, stainless steels, and nickel-based alloys, because of its high thermal diffusivity and low infrared absorptivity and tendency to result in relatively porous parts. Howev...
