iron alloysmetalsrelaxationA study was made of the temperature dependence of elasticity modulus and internal friction for copper M1, aluminum A00, commercial iron, brass L70, silumin AL2, gray cast iron SCh20, and white cast iron (2.2% C; 1.0% Si; 0.35% Mn, 0.03% S, 0.04% P) in ...
A method of calculating the anisotropy of the elastic properties in metals and alloys with a close-packed hexagonal structure in which limitations imposed on the type and character of dispersion of the crystallographic structure are absent has been developed and used. The anisotropy of Young's modul...

Shape memory alloys3—including gum metals4,5 and strain glass alloys6,7—may attain an elastic strain limit up to several per cent, although this is the result of pseudo-elasticity and is accompanied by large energy dissipation3. Recently, chemically complex alloys, such as ‘high-entropy...
The elastic moduli measured below the Curie temperature in this complex ferromagnet exhibit unusual lattice stiffening that is independent of the magnetic field and can be adequately modeled using the Landau theory.关键词: other ferromagnetic metals and alloys magnetic phase boundaries (including magnetic...
The Poisson's ratio of these materials was about 0.16 and 0.19 for TiAl3 and ZrAl3, respectively, and these values are much lower than those of ordinary metals and alloys. Debye temperatures were estimated at room temperature from the average velocity of ultrasonic waves and were 681 and 577...
The measuring of the constants of single-crystals requires the availability of crystals of relatively big size. In this paper the elastic constants of the single crystals of magnesium alloy with zinc, zirconium, and rare earth metals (REM) were determined by means of the experimental anisotropy of...

Nineteen transition metal elements have been taken into account to study the alloying effects on the relative phase stability, elastic properties and electronic structure of L12Co3V compound, based on the first-principles calculations. The site preference of ternary alloying elements was primarily determi...
