De-Ironing of Aluminium Alloy Melts by High Shear Melt Conditioning Technology: An Overview

Metals, 2022
The main problem of recycling aluminium scrap is the gradual accumulation of impurities, especially iron, which tend to form undesired intermetallic compounds that affect the integrity and the mechanical performance of the castings. In this paper, we aim

Segregation-dislocation self-organized structures ductilize a work-hardened medium entropy alloy

Nature Communications
Dislocations are the intrinsic origin of crystal plasticity. However, initial high-density dislocations in work-hardened materials are commonly asserted to be detrimental to ductility according to textbook strengthening theory.
