Wear of fine pearlite, nanostructured bainite and martensite
… of wear is complex and dependent on all the materials involved in the process, environmental conditions and many subtle factors such as the shape of the abrading particles. Many abrasion-resistant steels are based on a quenched and tempered martensitic microstructure, because the hardness of …

Aluminium foam production using calcium carbonate as a foaming agent
The current state of the art with regards to the production of metallic foams is reviewed, with melt-based processes identified as the most promising for cost-effective large-scale production. The potential for metal carbonates as an alternative to currently-used titanium hydride foaming agents is …

Erosion-oxidation of mild steel in a fluidized bed environment
This thesis is a contribution to research into erosion-corrosion investigating the rapid wastage of in-bed heat exchanger tubing in fluidized bed combustors. Two main new areas of research were investigated; erosion-corrosion of mild steel in a temperature gradient and erosion-corrosion modelling. …

Pulsed field magnetization of composite superconducting bulks for magnetic bearing applications
… remanent field of 1.4 T, whereas superconducting materials such as YBCO in their bulk form have the extraordinary ability to trap magnetic fields an order of magnitude higher, whilst being very compact. This gives them the potential to increase efficiency and allow significant volume and weight …
