Microstructural and Mechanical Characterization of Solidified Austenitic Stainless Steels

Archives of Foundry Engineering, 2017
Among the family of stainless steels, cast austenitic stainless steels (CASSs) are preferably used due to their high mechanical properties and corrosion resistance.

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

Effect of chromium content on the corrosion resistance of ferritic stainless steels in sulfuric acid solution

Heliyon, 2018
Due to recent increases in the price of Ni, steel use is currently undergoing a global shift from austenitic stainless steels to ferritic stainless steels.

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

steel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design

steel research international, EarlyView.
Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...

Effect of Grain Refinement on Deformation Mechanism and Mechanical Properties of Austenitic Stainless Steel

Cailiao gongcheng, 2016
The concept of phase reversion involving cold deformation of metastable austenite to generate strain-induced martensite, followed by temperature-time annealing sequence, was used to obtain grain size of nanograined/ultrafine-grained and coarse-grained ...

Influence of Heat Treatment Temperature on Crevice and Pitting Corrosion of UNS S32205 Duplex Stainless Steel

steel research international, EarlyView.
Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61
