The design of new die-castable bulk metallic glasses exhibiting superior mechanical performance. The most dramatic illustration of non-equilibrium processing of a metal is the formation of an amorphous solid that can possess physical and/or functional properties superior to its equilibrium crystalline counterpart. This project will generate new types of net-shape-processed amorphous alloys with an excellent combination of properties.

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

Summary
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. These new materials may also provide a platform for addressing the longstanding issues of relaxatio ....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. 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
