The potential for superlattice precipitate reinforcement in titanium-iron alloys
In the pursuit of novel structural metallic alloys, the concept of alloys featuring ordered B2 precipitates within a BCC matrix offers a promising possibility due to the potential synergistic benefits of a matrix with superlattice precipitates. The titanium-iron system is selected for this purpose, …

An Archaeometallurgical Study of Early Medieval Iron Technology. An examination of the quality and use of iron alloys in iron artefacts from Early Medieval Britain.
This project presents a study of iron technology in Early Medieval (fifth to eleventh centuries AD) Britain through the examination of iron found in settlement contexts. This is a period characterized by significant cultural, political and social changes. The effect of these changes on iron …

Effect of plastic strain on the corrosion of X65 pipeline steel
… an important mode of degradation and failure for iron alloys used in oil and gas pipelines. Pitting corrosion is a particular type of corrosion that is not well-understood and can play in important role in material failure. Research has shown that areas of increased plastic strain develop within …

Engineering and Optimisation of Materials and Components for Metal-Supported Solid Oxide Fuel Cells
… of inexpensive stainless steel and Ni-Fe (nickel-iron) alloys as substrate materials. Active layers, in the form of functional coatings, were deposited via a scalable and low-waste technique called Direct Ceramic Ink-Jet Printing. This method repeatedly produced coatings with 10-20 μm thicknesses, …

KMC modeling of helium bubble clustering and evolution in BCC iron
The effect of helium in iron is an important issue in nuclear systems, as iron and iron alloys (steels) are the primary materials used for structural elements. Helium is known to cause embrittlement and decrease fatigue life, as well as aid creep and promote swelling. These effects can …
