The utilization of the quantum properties of the electron spin wave function will allow the development of a new class of devices. The problem is still controversial and unsettled, even qualitatively, especially for concentrated spin systems such as 3d metals and their alloys. The variety of crystal structures of 3d metals makes difficult the direct comparison between the experimental results a...

Corrosion protection of metals and alloys is a prime activity of technical, economic, environmental, and aesthetical significance. The use of inhibitors is one of the best choice of combating metals and alloys against detoriation against environmental impact. The toxicity of organic and inorganic corrosion inhibitors to the environment has provoked the search for ecofriendly corrosion inhibitor...

Metal alloys consisting of a platinum group metal—ruthenium, rhodium, palladium, osmium, iridium or platinum—and one or more transition metals are important for catalytic reactions in automobiles, chemistry, and petroleum production. In addition, many of the alloys used in aeronautics and electronics contain platinum group metals. Alloys beyond those currently used in these industries could be ...

An ideal biomaterial is expected to exhibit properties such as a very high biocompatibility, that is, no adverse tissue response. Also, it must have a density as low as that of bone, high mechanical strength and fatigue resistance, low elastic modulus and good wear resistance. It is very difficult to combine all these properties in only one material. Some metals are used as biomaterials due to ...

We here study electronic structure and magnetic properties of disordered bcc CoxFe1−x, CrxFe1−x and MnxFe1−x alloys in their ferromagnetic phases using Augmented Space Recursion (ASR) technique coupled with tight-binding linearized muffin tin orbital (TB-LMTO) method. We calculate the densities of states, magnetic moments and Curie temperatures of these alloys to show the variation upon alloyin...

The Gibbs-Bogoliubov formalism in conjunction with the pseudopotential theory is applied to the calculation of the vapour pressure of eight liquid metals from Groups I to IV of the periodic table and of alloys (Na-K). The calculated vapour pressure o f the elements and their temperature dependencies, the partial pressures, activities and boiling points of the alloys are all found to be in reaso...

describe this work to a materials science and engineering professional with no experience in your technical specialty? This paper uses Poisson’s ratio as the screening parameter to identify potential ductilizing additives to the refractory elements such as chromium. First-principles density functional theory calculations are used to predict Poisson’s ratio of various chromium binary alloys. The...

Ternary amorphous W–xCr–yZr alloys containing 9−38 at % tungsten, 15−42 at % chromium and 39−73 at % zirconium were successfully prepared by direct current (DC) magnetron sputtering technique. The corrosion rates of all the examined sputter−deposited W–xCr–yZr alloys were in the range of 1 × 10−3 mm/y or lower which are nearly one order of magnitude lower than those of the sputter−deposited tun...

A systematic investigation of the magnetization and mechanical properties of amorphous NixFeso-,BlSSiz is reported. The magnetization showed strong depression for x 2 50. The alloys with x 2 65 are paramagnetic at room temperature but the Young's modulus (as well as microhardness) decreased almost linearly with x at 77 and 300 K. It was concluded that bonding was primarily due to d-electrons re...
