Fundamental understanding of the environmental factors essential for environmental assisted fracture (EAF) of cast magnesium alloys. This project proposes a combined theoretical and experimental approach to understand the key environmental factors causing EAF of commercial cast magnesium alloys. Rather than testing all possibilities, it is proposed to establish a mechanistic understanding for EAF, and to test and expand that understanding through key experiments. EAF is a particularly dangerous ....Fundamental understanding of the environmental factors essential for environmental assisted fracture (EAF) of cast magnesium alloys. This project proposes a combined theoretical and experimental approach to understand the key environmental factors causing EAF of commercial cast magnesium alloys. Rather than testing all possibilities, it is proposed to establish a mechanistic understanding for EAF, and to test and expand that understanding through key experiments. EAF is a particularly dangerous and complicated form of corrosion. Existing experience indicates that EAF incidence will increase as magnesium alloys are increasingly used in more challenging applications. The results and insights from this research will help to underpin a major new industry and industrial applications.Read moreRead less
Texture enhancement by inoculation in strip-cast metallic sheet. A recent discovery by the applicants has shown the possibility of producing, by inoculation during a direct casting route, stainless steel strip that exhibits a remarkably strong crystallographic alignment of grains perpendicular to the sheet surface.

A recent discovery by the applicants has shown the possibility of producing, by inoculation during a direct casting route, stainless steel strip that exhibits a remarkably strong crystallographic alignment of grains perpendicular to the sheet surface. The production of this so-called <001>//ND fibre texture in thin strip by direct casting represents a vastly simplified route for the possible production of iron-base strip suitable for some magnetic applications. The principle aims of the project are to elucidate the mechanisms of formation of this highly textured steel sheet and to explore the feasibility of reproducing the texture in other metallic systems.Read moreRead less
