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: In this paper, the effects of Mn and Al contents on tensile and Charpy impact properties in four austenitic high-Mn steels were investigated at room and cryogenic temperatures.

TL;DR: In this paper, a new ultra-high-strength (ferrite+austenite) duplex lightweight steels containing a low-density element of Al, which exhibit strength above 1 GPa and tensile elongation of 46%, have been developed.

TL;DR: In this paper, the authors investigated the origin of texture modification by Ca addition and showed that Mg-1Zn-1Ca (ZX11) alloy sheets in the as-rolled condition show the textures having a splitting of basal poles toward the rolling direction and a splitting on the transverse direction, respectively.
