Effect of ageing heat treatment on corrosion behaviorof 17-4 PH stainless steel in 3.5% NaCl
The 17-4PH alloy is a martensitic stainless steel with 3–5 wt% Cu, strengthened by the precipitation hardening. Due to excellent mechanical properties, corrosion resistance and ease of heat treatment, this alloy has unique applications in nuclear power plants and marine constructions. In this paper, the influence of ageing heat treatment, solution annealing followed by ageing at 480, 550 and 62...

متن کاملTowards sustainable machining of 17-4 PH stainless steel using hybrid MQL-hot turning process
The use of a minimum quantity of lubrication (MQL) with extremely low consumption of lubricant in machining processes has been reported as a technologically and environmentally feasible alternative to conventional flood cooling. In hot machining, the external heat source is applied during machining that will assist to increase machining performance. Many external heating techniques are availabl...
متن کاملMechanical properties and microstructural characterization of selective laser melted 17-4 PH stainless steel
Purpose – The purpose of this paper is to understand the effect of four different factors: building orientation, heat treatment (solution annealing and aging), thermal history and process parameters on the mechanical properties and microstructural features of 17-4 precipitation hardening (PH) stainless steel (SS) parts produced using selective laser melting (SLM). Design/methodology/approach – ...
متن کاملMicrostructures and Properties of 17-4 PH Stainless Steel Fabricated by Selective Laser Melting
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 C...
