Strength/elongation optimisation in alloys: A case for accelerated metallurgy research
Strength/elongation optimisation in alloys: A case for accelerated metallurgy research
Two novel techniques are combined for the design of novel alloys for enhanced strength/ductility relationships: (1) a principal component analysis on an extensive database of commercial alloys; and (2) thermostatistical modelling of alloy plasticity, which allows to capture the overall stress-strain curve as a function of composition and microstructure. The combined models are validated with hundreds of Fe-base alloys, and it is demonstrated that strength/ductility improvements are still possible by altering both microstructre and composition. By combining the models with a third approach, an artificial neural network, new alloys exhibiting strength/ductility relationships beyond existing technology are conceived. This fits within the Accelerated Metallurgy programme, a major European effort towards the discovery of novel alloys to satisfy modern industrial and environmental needs.

Abstract
Two novel techniques are combined for the design of novel alloys for enhanced strength/ductility relationships: (1) a principal component analysis on an extensive database of commercial alloys; and (2) thermostatistical modelling of alloy plasticity, which allows to capture the overall stress-strain curve as a function of composition and microstructure. The combined models are validated with hundreds of Fe-base alloys, and it is demonstrated that strength/ductility improvements are still possible by altering both microstructre and composition. By combining the models with a third approach, an artificial neural network, new alloys exhibiting strength/ductility relationships beyond existing technology are conceived. This fits within the Accelerated Metallurgy programme, a major European effort towards the discovery of novel alloys to satisfy modern industrial and environmental needs.
