Influence of Ausforming on the Micro‐ and Nanostructure of PH 13‐8 Mo Maraging Steels
steel research international, Volume 95, Issue 8, August 2024.The potential of the integration of ausforming into the heat treatment of PH 13‐8 Mo maraging steels is investigated. By performing ausforming, a refinement of martensite is achieved. Furthermore, the high number of induced nucleation sites can elevate the number density of β‐NiAl precipitates after aging.
