Performance through design

Alloys by design

Our proprietary ABD® software uses physics based-models developed over a decade by a world-leading research group at the University of Oxford to predict the behaviour of millions of alloy compositions instantaneously, allowing for accurate optimisation for specific target applications.

The software ‘merit indices’ derived from physical models with thermodynamic data to model composition performance on a number of key parameters, including creep resistance, stiffness, high temperature strength, creep rupture life and oxidation resistance. 

OxMet has already used its software to develop a range of novel compositions which promise significant improvement over nickel alloys in current use, including alloys for improved turbine discs, blades, and other high-temperature components of jet engines and turbochargers. It also is conducting promising research into titanium alloys which could transform biomedical implants, and aluminium alloys which could make cars lighter, more efficient, and more easy to recycle.

Processing

We also use a number of advanced processability models. Components made from high-performance materials are often complex to produce, and undergo extreme post-processing treatments. We model the material’s behaviour under these conditions to ensure our alloys can be produced as intended.

Additive manufacture

Additive manufacture or “3D Printing” is a revolutionary production technology which ultimately promises to make the manufacture of a wide range of alloy components more precise, more efficient, and cheaper. Instead of pouring molten metal into a mould or machining a shape from a block, additive manufacture builds up components layer-by-layer, without the need for expensive moulds or large factories.

OxMet has use its alloy development capability to invent, test, and demonstrate a family of nickel alloys which are specifically designed for the unique demands of additive manufacture, and do not suffer the cracking during printing which limits most other high-performance alloys.

It then applies its processing expertise to make powders and components from these alloys by powder-bed fusion. See our portfolio page for more details.
