Calculation of Surface Energy of metals and Alloys by theElectron Density Functional method

引用

Journal of materials Science & Technology 1998年第4期14卷 320-322页

作者： Kuznetsov, v.m. Kadyrov, R.I. Rudenskii, G.E. Institute of Strength Physics and material Science Russian Academy of Sciences Siberian Branch 634048 Tomsk Academicheskii av. 2/1 Russian Federation

The surface energy of (100), (110), (111) surfaces in Ni, Al and ordered alloys NiAl and Ni//3Al has been calculated within the framework of methodology based upon the electron density functional method. The results of calculations are in good agreement with the known for pure metals experimental data and in case of Ni//3Al alloy. There is also a good agreement with the results obtained by calculation using the embedded atom method. The investigation has been carried out in this work to show that the surface energy sigma of alloys can not be interpreted as an averaged concentration sigma of pure metals. For NiAl, the obtained results reveal considerable distinctions in anisotropy of sigma in comparison to the anisotropy of surface energy in pure metals. (Edited author abstract) 8 Refs.

many-body Interatomic Potentials for Computer Simulation of Physical Processes in metals and Alloys

引用

Journal of materials Science & Technology 1998年第5期14卷 429-433页

作者： Kuznetsov, v.m. Rudenskii, G.E. Kadyrov, R.I. Kaminskii, P. Institute of Strength Physics and material Science Russian Academy of Sciences Siberian Branch 634048 Tomsk Academicheskii av. 2/1 Russian Federation

A model of binding forces in metals and alloys, based on the density functional theory and accounted effects of the many-body interactions, was proposed. The developed method can be easily applied for study of metals and alloys by the molecular dynamics simulation. The potentials of interatomic interactions have been found by the proposed method and applied for calculations of equation of state, elastic moduli and phonon dispersion in metals Ni, Al, and alloys NiAl, Ni//3Al. Results of the calculations are in good agreement with known experimental data both for pure metals and alloys. (Edited author abstract) 16 Refs.

Box 522 11001 Serbia Laboratory of Physical Chemistry Vina Institute for Nuclear Sciences University of BelgradeP.O. Box 522 11001 Serbia

Interaction of pulsed transversely excited atmospheric （TEA） CO2-1aser radiation at 10.6 μm with nanoporous activated carbon cloth was investigated. Activated carbon cloth of different adsorption characteristics was used. Activated carbon cloth modifications were initiated by laser pulse intensities from 0.5 to 28 mW/cm^2, depending on the cloth adsorption characteristics. CO2 laser radiation was effectively absorbed by the used activated carbon cloth and largely converted into thermal energy. The type of modification depended on laser power density, number of pulses, but mostly on material characteristics such as specific surface area. The higher the surface area of activated carbon cloth, the higher the damage threshold.

Sound scattering in dense granular media

引用

Chinese Science Bulletin 2009年第23期54卷 4327-4336页

作者： laurent J KHIDAS Y LANGLOIS v Laboratoire de Physique des matériaux Divisés et des Interfaces Université Paris-Est

The sound propagation in a dense granular medium is basically characterized by the ratio of wavelength to the grain size. Two types of wave transport are distinguished: one corresponds to coherent waves in the long wavelength limit, the other to short-wavelength scattered waves by the inhomogeneous contact force networks. These multiply scattered elastic waves are shown to exhibit a diffusive characteristics of transport over long distances of propagation. Determination of the transport mean free path l * and the inelastic absorption (Q-1) allows the inference of the structural properties of the material such as the heterogeneity and internal dissipation. The relevance of our experiments for seismological applications is discussed. moreover, we apply the correlation technique of the configuration-specific sound scattering to monitoring the dynamic behaviour of the granular medium (irreversible rearrangements) under strong vibration, shearing and thermal cycling, respectively.

Objective： To evaluate the surgical clinical results of hypertrophic obstructive cardiomyopathy. methods： We retrospectively collected data on 24 patients who underwent surgical management in the past ten years in two hospitals in China and madras medical mission in India. myomectomy was carried out on all patients. Among them 3 patients underwent mitral valve replacement; 2 patients underwent mitral valve repair （anterior mitral leaflet plication）; 2 patients underwent aortic valve replacement; 1 patient underwent aortic valve repair; 2 patients underwent aortic root replacement; 1 patient underwent Bentall＇s procedure and 1 patient underwent coronary artery bypass grafting because of a breached muscle bridge, Results： One patient died of post-operative heart failure. The mean follow-up time was 4.3 years, There was significant improv.m.nt in the symptomatic status. Sixteen patients were asymptomatic with good effort tolerance and only four patients had New York heart association （NYHA） Classes Ⅰ-Ⅱ due to associated valvular lesions, Conclusion： Our experience proved that symptomatic hypertrophic obstructive cardiomyopathy or non-symptomatic hypertrophic obstructive cardiomyopathy with combined heart disease is indication for surgery as surgical intervention could get better clinical results in this kind of patients compared with other non-surgical method because it beneficially reduces the systolic anterior motion （SAm） of the mitral valve leaflet, which could not be avoided by other non-surgical treatment.

Precipitation analysis of as-cast HK40 steel after isothermal aging

International Journal of minerals,metallurgy and materials 2017年第10期24卷 1125-1133页

As-cast HK40 steel was aged at 700, 800, or 900℃ for times as long as 2000 h. microstructural characterization showed that the primary m_7C_3 carbide network contained a substantial content of manganese, in agreement with the microsegregation of manganese calculated by Thermo-Calc using the Scheil–Gulliver module. The dissolution of primary carbides caused the solute supersaturation of austenite and subsequent precipitation of fine m_(23)C_6 carbides in the austenite matrix for aged specimens. During prolonged aging, the carbide size increased with increasing time because of the coarsening process. A time–temperature–precipitation diagram for m_(23)C_6 carbides was calculated using the Thermo-CalcPRISmA software; this diagram showed good agreement with the experimental growth kinetics of precipitation. The fine carbide precipitation caused an increase in hardness; however, the coarsening process of carbides promoted a decrease in hardness. Nanoindentation tests of the austenite matrix indicated an increase in ductility with increasing aging time.
