Strenghtening mechanisms of Specialisr

๐Ÿ’ก Deep dive into the strengthening mechanisms of world's hardest LPBF maraging tool steel Specialis® on #MaterialsMonday

Kudos to our partners at IAM-WK: Institute for Applied Materials, KIT and especially Niki Nouri for publishing the great research paper with the title "Characterization of phase transformation and strengthening mechanisms in a novel maraging steel produced using laser-based powder bed fusion"

Highlights of the paper:
๐Ÿ‘‰ Addition of V and Al leads to grain refinement in maraging steels.
๐Ÿ‘‰ Intermetallic phases Ni3Ti and Fe2Mo are identified as hardening precipitates.
๐Ÿ‘‰ The contributions of Hall-Petch and Orowan strengthening are separately calculated.

๐Ÿ‘‰ The calculations show good agreement with the measured tensile strength difference.
