TL;DR: It is shown that an FeAl-type brittle but hard intermetallic compound (B2) can be effectively used as a strengthening second phase in high-aluminium low-density steel, while alleviating its harmful effect on ductility by controlling its morphology and dispersion.

TL;DR: A reason why the success of lightweight steels is strongly dependent on scientific achievements even though alloy development is closely related to industrial applications is provided.

TL;DR: The authors use precipitation and elemental segregation to design a magnesium alloy with high strength and high formability, which is expected to broaden the application of Mg alloy sheets, which are now starting to gain acceptance by automotive industries.

TL;DR: In this paper, critical issues relating to the strength and formability of Mg sheet alloys are assessed and it is suggested that future research and development efforts should be concentrated on identifying the alloying elements and optimizing the related processes that can accelerate the agehardening response and modify the texture to be weak and symmetric.

TL;DR: The results demonstrate that non-recrystallized grains, which are generally avoided in conventional alloys because of their deleterious effect on ductility, can be useful in achieving high-strength high-entropy alloys.
