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

Ultrastable metallic glasses. The aim of this project is to create a new class of amorphous alloy – ultrastable metallic glass – by a relatively simple vapour-deposition route. These materials are expected to exhibit unprecedentedly low energy states and properties of high thermal stability, elastic modulus, strength, and hardness not achievable in metallic glasses produced by conventional routes.

The aim of this project is to create a new class of amorphous alloy – ultrastable metallic glass – by a relatively simple vapour-deposition route. These materials are expected to exhibit unprecedentedly low energy states and properties of high thermal stability, elastic modulus, strength, and hardness not achievable in metallic glasses produced by conventional routes. These new materials may also provide a platform for addressing the longstanding issues of relaxation dynamics in glassy physics. The unique properties of ultrastable metallic glasses are expected to make them useful in a range of applications, including highly wear- and corrosion-resistant coatings on electronics and biomedical devices and components.Read moreRead less

Ultra-lightweight alloys with unique multi-dimensional property profiles. Lightweight alloys with high specific-strength are an essential prerequisite in modern and future technologies. To be useful, they must also possess ductility and inherent corrosion resistance. The latter two properties, however, are inversely correlated with strength.

Lightweight alloys with high specific-strength are an essential prerequisite in modern and future technologies. To be useful, they must also possess ductility and inherent corrosion resistance. The latter two properties, however, are inversely correlated with strength. This project proposes to break this paradox - not only in terms of a paradigm change regarding multi-property alloy design - but as applied to the most lightweight engineering alloy system in existence, Magnesium-Lithium (Mg-Li), for which the impact on specific properties is immense. The aim is to develop ultra-lightweight Mg-Li based alloys with formidable property profiles via alloy design and thermomechanical processing. The expected outcome is a new class of structural corrosion resistant metal.Read moreRead less
