金属学报(英文版) , 1993,
Abstract: Crystal structure of γ-Li_xFe_2O_3,inserted Li electrochemically,was studied by Moss-bauer spectroscopy together with X-ray diffraction,XPS and electrochemical method,Onthe insertion of Li at low current density,the crystal structure is keeping original spinel;while at higher current density or by thermal activation,owing to violent movement ofLi~+ ions,part of crystal structure transforms into rock type similar to face-centeredcubic structure of ferrous oxide.The transition channels during insertion of Li~+ ions andlimitation of Li~+ ions inserted were discussed.

Abstract: The TiN films were synthesized with an alternate process of depositing titanium from a E-gunevaporation source and 40 keV N~+ bombarding onto the target.It is shown from the composi-tion analysis and structure investigations using RBS,AES,TEM,XPS and X-ray diffractionspectrum that the formed fihns are mainly composed of TiN phase with grain size of 30—40nm and without preferred orientation,the nitrogen content in the film is much less than that incase without N~+ bombarding,and an intermixed region about 40 nm thick exists between thefilm and the substrate.The films exhibt high microhardness and low friction.

Abstract: The TiN film was synthesized by alternate deposition of Ti and nitro-gen ion bombardment under 40 keV at room temperature. The component depthprofiles and the structure of the film have been investigated by means of RBS,AES, TEM, XPS and X-ray diffraction. The results showed that the TiN films syn-thesized by ion beam enhanced deposition (IBED) are mainly composed of TiNcrystallites, sized about 30-40 nm, with random orientation. The oxygen contaminationin TiN film prepared by IBED is less than that of the deposited film without nitrogenion bombardment. It was confirmed that there is a significant intermixed layer, about40nm thick, at the interfaces. The films formed by IBED exhibit superior hardnessand improvement over the wear resistance and frictiton properties.

Abstract: Pattern recognition method is used for the investigation of stability,region of filled Ti_2Ni phases in multi-dimensional bond-parameter space.The filling of C,N and O atoms into T_6 octahedra consisting of atoms of earhy-transition elements makes the expansion of the stability region of Ti_2Ni phase,and the relative stability of AI_2Cu and MoSi_2 type com- pounds decreases after the introduction of non-metallic elements such as C,N and O.

Abstract: A new Kossel orientation method of crystal is developed.Only the distances among three in- tersections of the Kossel lines on the indexed Kossel patterns observed are necessary.for de- termining the orientation.Thus,the error may be eliminated and the orientation precision may be improved to be within 0.3°.

Abstract: The regularity of the carbonization process in alumina production has been summarized by the pattern recognition and regression.A mathematical model has been proposed to describe the factors affecting the silica content of aluminium hydroxide product.The high concentration of aluminate ions in solution will produce aluminium hydroxide with low content of SiO_2 under the condition of Al_2O_3/SiO_2 ratio kept unchanged.This was confirmed by certain scale experiments.

Abstract: The structure and behaviour of LiF-KF solution,as a typical common-anion system,has been simulated by Monte Carlo method.The calculation of partial radial distribution function of ions,heat of mixing and potential energy distribution shows that the average distance be- tween Li~+ and F~- ions will significantly narrow after mixing of molten LiF and KF.This is very similar to the lean-on-one-side effect in molten LiF-KCl solution.The calculated heat of mixing is in fair agreement with the measured one.The dominant source of the energy of mixing may be that the decrease of the repulsion energy between cations,the decrease of the attraction energy between cations and anions,and the decrease of the repulsion energy be- tween anions.
