This thesis aims to examine the modes of production and the sources of metal supply for Migration period bow brooches, concentrating on a single form, the Anglian cruciform brooch.
The thesis is in two volumes; text and bibliography (volume 1), catalogues, tables, illustrations (volume 2). The text is in six chapters.
Attitudes to artefact studies are briefly discussed in Chapter 1 and the techniques employed in this study are o ... [truncated at 450 characters in length]

Austenitic stainless steels are frequently used in the cooling circuits of nuclear reactors. It has been found that cold-worked 304 stainless steels can be particularly susceptible to stress corrosion cracking at the operating conditions of such reactors. Despite more than 130 years of research underlying mechanisms are still not properly understood. For this reason, the effects of cold-work and applied stress on the oxidation behaviour of 304 ...

|Abstract||This thesis describes the design, manufacture and characterisation of thick vacuum plasma sprayed tungsten (W) coatings on steel substrates. Fusion is a potentially clean, sustainable, energy source in which nuclear energy is generated via the release of internal energy from nuclei. In order to fuse nuclei the Coulomb barrier must be breached - requiring extreme temperatures or pressures – akin to creating a ‘star in a box’. Tungsten is a promisi ...
