Pumps working as turbines as an engineering solution for energy recovering in water distribution systems
Design of multi-major-component (high entropy) alloys of suitable magnetic and mechanical properties based on a Hume-Rothery approach M major component alloys (also called high entropy alloys (HEAs)) appeared around 2004. They are based on 4 or more elements in close to equimolar composition. The equal footing of each element on solidification leads to an interesting new metallurgy providing materials with promising properties. The design of HEAs is thus a challenge to improve traditional compositions with possibly cheaper or greener components. The present work reports a strategy for the design of HEAs with suitable magnetic and mechanical properties based on a Hume-Rothery approach, namely on the calculation of the number of itinerant valence electrons and the average atomic radius for 12 atoms neighborhood. Prediction algorithms based on self-ordering maps permit to improve the composition choice.
