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

open access: yesMaterials and Corrosion, EarlyView.
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

Failure Investigation of Alloy 625 Sockolets After Prolonged Service in an Ammonia Cracker Unit

open access: yesMaterials and Corrosion, EarlyView.
The failure of the sockolets was caused by intergranular cracking and fracture. The thick and highly brittle nitrided layer formed intergranular surface cracks, which propagated along grain boundaries into the base alloy substrate due to the presence of brittle Cr‐rich carbides. ABSTRACT Several sockolets of Alloy 625 operating at 540°C in contact with

Experimental and Comparative Study of the Corrosion Behavior of Lean Duplex Stainless Steel in Seawater

open access: yesMaterials and Corrosion, EarlyView.
The localized corrosion behavior of lean duplex stainless steel EN 1.4062 is systematically compared with austenitic and higher‐alloyed duplex grades in natural seawater. A clear resistance ranking is established, highlighting EN 1.4062 as a cost‐effective alternative for limited marine exposure.

Interface Phonon Transmission Behaviors and Their Resultant Influence on Thermal Transport in Cu/Diamond Composites

open access: yesMaterials Genome Engineering Advances, EarlyView.
Cu/diamond heat spreaders are limited by low thermal boundary conductance. Using DFT + DMM, we identify the phonon‐transport factors governing TBC and show that optical–phonon contributions and branch conversion are essential. High‐k $k$ carbides (B4C, WC) and residual B and Cr improve interfacial heat transfer, enabling robust performance versus ...
