TL;DR: A group of alloys that exhibit “super” properties, such as ultralow elastic modulus, ultrahigh strength, super elasticity, and super plasticity, at room temperature and that show Elinvar and Invar behavior are described.

TL;DR: In this paper, the elastic constants of the polycrystals for these Ti or Zr binary alloys were calculated using the Voigt-Reuss-Hill averaging scheme, and it was shown that the Young's moduli of these polycrystal alloys have the minimum values in the vicinity of 0.25.

TL;DR: In this article, the effect of cold working on the elastic properties of a newly developed multi-functional β titanium alloy, GUM METAL, using in-situ XRD and EBSP analysis was investigated.

TL;DR: In situ X-ray diffraction measurements under tensile loading and dynamic mechanical analysis were performed to investigate the mechanisms of elastic deformation in Gum Metal as discussed by the authors, which indicated that cold working substantially decreases the elastic modulus while increasing the yield strength, thereby confirming nonlinearity in the elastic range.

TL;DR: A process for compacting a green compact includes the steps of applying a higher fatty acid-based lubricant to an inner surface of a die, filling a raw material powder whose major component is an active metallic element into the die, compacting the powder by warm pressurizing, and ejecting the green compact from the die as mentioned in this paper.
