The Behavior of Phosphorus in the Hydrogen‐Based Direct Reduction—Smelter Ironmaking Route

steel research international, Volume 95, Issue 11, November 2024.
As phosphorus is considered harmful for steel properties, its behavior in hydrogen‐based direct reduction (DR) and smelting is investigated. Apatite remains stable in DR and significant amounts of phosphorus are expected to remain in the smelter slag.

Microstructural evolution of a low-alloy steel / nickel superalloy dissimilar metal weld during post-weld heat treatment [PDF]

arXiv, 2019
The microstructural evolution of a dissimilar metal weld (DMW) obtained by narrow-gap gas tungsten arc welding (NG-GTAW) was investigated after it was subjected to a post-weld heat treatment (PWHT). The case studied here is a joint between low-alloy steel pipes and a stainless steel steam generator using a nickel based alloy as filler material.
