Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, Volume 28, Issue 13, 8 July 2026.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Effect of Heat Treatment Parameters on Microstructure, Hardness, and Corrosion Resistance of Martensitic Stainless Steel X30Cr13 (AISI 420B)

Materials and Corrosion, Volume 77, Issue 7, Page 1094-1105, July 2026.
The hardness and corrosion resistance of the martensitic stainless steel X30Cr13 depend directly on the applied heat treatment. This article describes and discusses the relationships between alloy composition, thermodynamic phase stabilities, heat treatment parameters, resulting microstructures, and achievable corrosion resistance. To investigate these

Intergranular corrosion of TiNb-microalloyed martensitic stainless steels processed by quenching and partitioning

Journal of Materials Research and Technology
This study investigates the localised corrosion mechanisms in laboratory-processed Q&P-treated martensitic stainless steels. Two steel variants, one NbTi-free (alloy B) and the other micro-alloyed with Nb and Ti (alloy M) were investigated to elucidate ...

Reversed Austenite for Enhancing Ductility of Martensitic Stainless Steel

IOP Conference Series: Materials Science and Engineering, 2017
Quenching and partitioning (Q&P) heat treatment increases the deformability of high-strength martensitic steels. Therefore, it is necessary to have some metastable austenite in the microstructure, which transforms in martensite during plastic deformation (TRIP effect).
