Analysis of Corrosion and Wall Perforation in the Heat Exchanger Made of AISI 316L Stainless Steel

Materials and Corrosion, EarlyView.
Elevated passivation temperature is identified as the dominant factor triggering localized corrosion and subsequent perforation of AISI 316L heat exchanger tubes. Electrochemical and complementary characterization results show that the alloy retains high resistance to general, pitting, and intergranular corrosion, indicating that failure primarily ...

Austenite and ferrite grain size evolution in plain carbon steel [PDF]

, 1995
Grain size evolution in a 0.17%C, 0.74%Mn plain carbon steel is investigated using a Gleeble 1500 thermomechanical simulator. Austenite grain growth measurements in the temperature range from 900 to 1150{degrees}C have been used to validate the ...

Acoustic Activity of Intergranular Corrosion Sensitized AISI 304L in Double‐Loop Electrochemical Potentiodynamic Reactivation Test

Materials and Corrosion, EarlyView.
Intergranular corrosion of AISI 304L is analyzed, combining DLEPR test and AE. Slow scan rate polarization reveals time‐shifted and frequency‐dependent acoustic emission in the active region of the DLEPR curve, allowing a separation between passive oxide rupture, intergranular corrosion and pitting. ABSTRACT Intergranular corrosion (IGC) susceptibility

Overlap Percentage Effects on Microstructure and Microhardness in Wire Arc Additive Manufacturing of AISI 308L Stainless Steel

MetalMat, EarlyView.
Overlap percentage governs the remelting, dilution, and solidification behavior of CMT‐WAAM AISI 308L stainless steel. Increasing overlap to 50% promotes stronger bead‐to‐bead bonding, wider transition zones, and localized hardness enhancement, with the highest hardness observed in the overlap region due to grain refinement and δ‐ferrite redistribution.

Influence of Heat Treatment and Scan Rotation on the Microstructure of Hot Work Tool Steel Manufactured using Laser Powder Bed Fusion

steel research international, EarlyView.
The study investigates the influence of heat treatment and scan rotation on the microstructure of a modified H13 tool steel manufactured using laser powder bed fusion. Key findings include the refinement of prior austenite grains (PAGs) due to recrystallization and carbide pinning, and the significant impact of scan rotation on the size distribution of

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.
