Objective
The core concept of Accelerated Metallurgy is to deliver an integrated pilot-scale facility for the combinatorial
synthesis and testing of many thousands of unexplored alloy formulations. This facility would be the first of its kind in
the world and would represent a significant advance for metallurgy. The novel technology that enables this HTT facility
is based on automated, direct laser deposition (DLD). The key feature of this technology is the way in which a mixture
of elemental powders is accurately and directly fed into the laser's focal point, heated by the laser beam, and
deposited on a substrate in the form of a melt pool, which finally solidifies to create a unique fully-dense alloy button
with precise stoichiometry. This robotic alloy synthesis is 1000 times faster than conventional manual methods. Once
produced, these discrete mm-sized samples are submitted to a range of automated, standardised tests that will
measure chemical, physical and mechanical properties. The vast amount of information will be recorded in a ""Virtual
Alloy Library"" and coupled with computer codes such as neural network models, in order to extract and map out the
key trends linking process, composition, structure and properties. The most promising alloy formulations will be further
tested, patented and exploited by the 20 end-users. Industrial interests include: (i) new lightweight fuel-saving alloys
(<4.5 g/cm3) for aerospace and automotive applications; (ii) new higher-temperature alloys (stable>1000°C) for rockets,
gas turbines, jet-engines, nuclear fusion; (iii) new high-Tc superconductor alloys (>30K) that can be wire-drawn for
electrical applications; (iv) new high-ZT thermoelectric alloys for converting waste heat directly into electricity; (v) new
magnetic and magnetocaloric alloys for motors and refrigeration; and (vi) new phase-change alloys for high-density
memory storage. The accelerated discovery of these alloy formulations will have a very high impact on society.
