Rationalisation of Al-alloy grades and specifications

One of the adverse consequences of dissipative use of metallic materials is that there are currently thousands of grades of metallic materials in commercial use today. Many of them differ only slightly in composition, processing conditions or origin of production, offering essentially the same performance. Unnecessary alloying elements and excessively tight alloy specifications increase production costs, reduce resource productivities, cause more environmental damage, and make the end-of-life products difficult (if not impossible) to recycle. This is not compatible with Circular Economy (EC) principles. Recycling can be improved significantly with materials rationalised and products engineered from the start for this purpose.

This project aims to rationalise alloy grades and specifications of aluminium alloys to facilitate full metal circulation. The project contributes to slowing the resource loop by design for standardisation and compatibility. The specific research activities include: (1) simplification of alloy systems based on their compositions, thermomechanical history, levels of performance and fields of application; (2) standardisation of alloy compositions by using commonly available alloying elements and avoiding the recyclability-limiting elements; (3) optimisation of thermomechanical treatment procedures for high performance; and (4) development of new alloy specifications.

The funding amount is £88,918 for 4 years duration.

Dr Chamini Mendis - Dr. Chamini Mendis is the newly appointed Reader in Mg research. Prior to this, she was a research scientist at the Magnesium Innovation Centre (MagIC) in the Helmholtz-Zentrum Geesthacht in Germany. She received her Ph.D. (2005), M.Eng.Sci. (2000) and BE/LLB (1995/1997)) in Materials Engineering from the Monash University, Australia. Following the doctoral studies, prior to moving to MagIC,  she spent 6 years at the National Institute for Materials Science (Tsukuba, Japan) working with Prof. Kazuhiro Hono, first as a JSPS postdoctoral fellow and then as a MANA researcher, the design and characterization of light metallic materials especially newly developed precipitation hardable magnesium alloys, with a special focus on the characterization of nano-scaled particles using advanced transmission electron microscopy and 3 dimensional atom probe tomography. She has published over 100 research publications including research papers in scientific journals, conference proceedings and a book chapter. She is a member of the magnesium committee The Materials Metals and Mineral Society (TMS) was a guest editor of the institute journal JOM. Her current research interest includes development of new advanced magnesium alloys for structural applications using low cost alloying additions for both cast and wrought applications, microstructure property relationships of light alloys, solid-state phase transformations in light metallic alloys with focus on Mg alloys and solidification and thermomechanical processing of Mg alloys.
