Computational thermodynamic analysis of secondary phases in super . . .
Materials Sciences and Applications, 2015 Super duplex stainless steel (SDSS) is considered as a composite formed from a microstructure of an approximately equal mixture of two primary constituents (γ-austenite and α-ferrite phases) and the secondary precipitates (sigma, chi, alpha-prime, etc )
Origins of twin boundaries in additive manufactured stainless steels
316L and 304L stainless steels and a compositional gradient of both are fabricated using the same processing parameters via laser directed energy deposition additive manufacturing In those alloys, the increase in chromium-to-nickel ratio is accompanied with grain refinement and formation of a high density of twin boundaries, i e Σ3 boundaries

Density of Stainless Steel 310 is assumed to be constant at 7 829 g cm 3 ¹ References: Blumm, J , Lindemann, A , Niedrig, B et al , “Measurement of Selected Thermophysical Properties of the NPL Certified Reference Material Stainless Steel 310,” Int J Thermophys
(PDF) Advanced Electric Discharge Machining of Stainless Steels . . .
The effect of the EDM process on the mechanical behaviour of stainless steel has been studied by many researchers such as [224] Jha, et al [195] studied the role played by the EDM process in the fatigue performance of 15-5 PH stainless steel The study conducted qualification tests of a piston workpiece made of the given stainless steel
Prediction of Nitrogen Content of Steel Melt during Stainless Steel . . .
Equilibrium Nitrogen Concentration for Cr–Ni Stainless Steel For Cr–Ni stainless steel equation proposed by Riipi et al has been used to predict the equilibrium nitrogen concentration in steel melt [7] ½N wt% ¼ ð40Þ log f N where, logK ¼ 664 T ð41Þ 0:999 so Equation 40 becomes log½%N ¼ 664 T 0:999 log f N logf N ¼ log f alloy N

Additively Manufactured 316L Stainless Steel: Effect of Heat Treatment . . .
Email: shamsaei@auburn edu Phone: (334) 844 4839 Abstract The microstructure and tensile properties of 316L stainless steel (SS) fabricated using the laser powder directed energy deposition (LP-DED) after various heat treatment (HT) steps such as stress-relief (SR), solution annealing (SA), and hot isostatic pressing (HIP) are characterized
(PDF) Stainless Steels for Design Engineers - Academia. edu
Academia edu is a platform for academics to share research papers Stainless Steels for Design Engineers Stainless steels, especially the grade used in this study, suffer from lower toughness caused by secondary phase precipitation especially when these steels undergo thermal treatments In this study the infl uence of thermal treatment
