Alloy Solutions for Ammonia Cracking: A Review

Materials and Corrosion, EarlyView.
This work provides a literature overview of the nitriding and degradation of structural materials under ammonia cracking conditions and explains the known mechanisms and the gaps, where research is required. ABSTRACT Hydrogen is a key factor in energy storage and transportation, which will inevitably lead to a substantial increase in demand.

Stability of retained austenite in martensitic high carbon steels. Part I: Thermal stability [PDF]

Materials Science and Engineering: A, 2018
Thermal stability of retained austenite in 1C-1.5Cr steels with two Si and Mn contents is studied. Time-resolved high resolution synchrotron X-ray radiation and dilatometry are employed. The threshold transformation temperatures, decomposition kinetics, associated transformation strain, as well as the influence of Si and Mn were investigated.

Experimental Evaluation of Turning AISI 304 Using Minimum Quantity Lubrication With Vegetable‐Based Green Cutting Fluids

MetalMat, EarlyView.
This study experimentally evaluates the performance of eco‐friendly vegetable‐based cutting fluids—coconut, sunflower, and palm oils—during turning of AISI 304 stainless steel under minimum quantity lubrication. Palm oil exhibited superior lubrication and cooling characteristics, yielding the lowest cutting force, temperature, and surface roughness ...

The Dependence of Properties on Structural Features in Macro/Micro Levels for PBF‐LB Fabricated Porous NiTi Alloy

Rare Metals, EarlyView.
ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...
