This article is dedicated mostly to the metallurgical effects on the corrosion behavior of CRA.
For each specific alloy, a metallurgical effect is considered when the overall composition of the
alloy is the same; however, the corrosion performance could change due to the presence of second
phases or a weld seam.
Before going into detail on the metallurgical effects, a brief introduction on the importance of alloying elements on the corrosion behavior of nickel alloys is presented. Moreover, a brief description is given of the corrosion applications of HRA.
