Application Prospect and Effect of Rare Earth Elements in Ferritic Stainless Steels

Teshugang, 2008
The anti-pitting corrosion,anti-stress corrosion and high temperature anti-oxidizing properties of ferritic stainless steels(11%～30%Cr)are better than that of austenitic stainless,but normal feritic stainless steels have higher ...

Laves phase precipitation behavior and high-temperature strength of W-containing ferritic stainless steels

Journal of Materials Research and Technology, 2020
Small-size Laves phase precipitates have the advantage of providing superior high-temperature properties to ferritic stainless steels. However, the coarsening of precipitates becomes inevitable during long-term service at elevated temperatures, which ...

Regulating the Boron Content to Suppress Stress‐Relief Cracking in the Coarse‐Grained Heat‐Affected Zone of 7CrMoVTiB10.10 Heat‐Resistant Alloy

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT This study demonstrates a new strategy for modifying the boron content to address stress‐relief cracking (SRC) in the 7CrMoVTiB10.10 alloy. First, coarse‐grained heat‐affected zone (CGHAZ) specimens with different boron contents were prepared via simulated welding thermal cycles.

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

Advanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability
